Anemia Is Associated with Disease Severity, Hepatic Complications, and Progression of Wilson Disease: A Retrospective Cohort Study.

INTRODUCTION: Anemia is a common manifestation of chronic liver diseases. It is a predictor of severe disease, a high risk of complications, and poor outcomes in various liver diseases. However, it remains unclear whether anemia serves as a similar indicator in patients with Wilson disease (WD). Therefore, this study aimed to investigate the relationship between anemia and severity, hepatic complications, and the progression of WD. METHODS: Medical data were collected retrospectively from January 1, 2016, to December 31, 2020. Univariate and multivariate analyses were carried out to investigate the relationship between anemia and liver-associated disease severity, hepatic complications, and the progression of WD. RESULTS: A total of 288 WD patients (48 with and 240 without anemia) were enrolled in the study. Multivariate linear regression revealed that WD patients with anemia had significantly higher levels of bilirubin, alanine transaminase, prothrombin time, international normalized ratio, type Ⅳ collagen, and hyaluronic acid and significantly lower levels of albumin, total cholesterol, and high-density lipoprotein-cholesterol (all p < 0.05). Multivariate logistic regression showed that anemia was a risk factor for gastric varices and ascites (all p < 0.05). Fully adjusted Cox regression revealed that anemia was an independent risk factor for advanced Child-Pugh classification (p = 0.034). CONCLUSIONS: Anemia was common in WD patients and was associated with greater disease severity, a higher risk of hepatic complications, and a faster progression.

Optical coherence tomography in patients with Wilson's disease.

BACKGROUND: Morphological changes of retina in patients with Wilson's disease (WD) can be found by optical coherence tomography (OCT), and such changes had significant differences between neurological forms (NWD) and hepatic forms (HWD) of WD. The aim of this study was to evaluate the relationship between morphological parameters of retina and brain magnetic resonance imaging (MRI) lesions, course of disease, type of disease, and sexuality in WD. METHODS: A total of 46 WD patients and 40 health controls (HC) were recruited in this study. A total of 42 WD patients were divided into different groups according to clinical manifestations, course of disease, sexuality, and brain MRI lesions. We employed the Global Assessment Scale to assess neurological severity of WD patients. All WD patients and HC underwent retinal OCT to assess the thickness of inner limiting membrane (ILM) layer to retinal pigment epithelium layer and inner retina layer (ILM to inner plexiform layer, ILM-IPL). RESULTS: Compared to HWD, NWD had thinner superior parafovea zone (108.07 ± 6.89 vs. 114.40 ± 5.54 µm, p < .01), temporal parafovea zone (97.17 ± 6.65 vs. 103.60 ± 4.53 µm, p < .01), inferior parafovea zone (108.114 ± 7.65 vs. 114.93 ± 5.84 µm, p < .01), and nasal parafovea zone (105.53 ± 8.01 vs. 112.10 ± 5.44 µm, p < .01) in inner retina layer. Course of disease influenced the retina thickness. Male patients had thinner inner retina layer compared to female patients. CONCLUSION: Our results demonstrated that WD had thinner inner retina layer compared to HC, and NWD had thinner inner retina layer compared to HWD. We speculated the thickness of inner retina layer may be a potential useful biomarker for NWD.

Analysis of risk factors for neurological symptoms in patients with purely hepatic Wilson's disease at diagnosis.

OBJECTIVE: To analyze and explore the risk factors for neurological symptoms in patients with purely hepatic Wilson's disease (WD) at diagnosis. METHODS: This retrospective study was conducted at the First Affiliated Hospital of the Guangdong Pharmaceutical University on 68 patients with purely hepatic WD aged 20.6 ± 7.2 years. The physical examinations, laboratory tests, color Doppler ultrasound of the liver and spleen, and magnetic resonance imaging (MRI) of the brain were performed. RESULTS: The elevated alanine transaminase (ALT) and aspartate transaminase (AST) levels and 24-h urinary copper level were higher in the purely hepatic WD who developed neurological symptoms (NH-WD) group than those in the purely hepatic WD (H-WD) group. Adherence to low-copper diet, and daily oral doses of penicillamine (PCA) and zinc gluconate (ZG) were lower in the NH-WD group than those in the H-WD group. Logistic regression analysis showed that insufficient doses of PCA and ZG were associated with the development of neurological symptoms in patients with purely hepatic WD at diagnosis. CONCLUSION: The development of neurological symptoms in patients with purely hepatic WD was closely associated with insufficient doses of PCA and ZG, and the inferior efficacy of copper-chelating agents. During the course of anti-copper treatment, the patient's medical status and the efficacy of copper excretion should be closely monitored.

Elderly onset of MELAS in a male: A case report.

Background: Mitochondrial encephalomyopathy with lactic acidosis and stroke-like episodes (MELAS) is one of the most common maternally inherited mitochondrial diseases which rarely affects elderly people. Case presentation: We reported the case of a 61-year-old male patient with MELAS. He was experiencing acute migraine-like headaches as the first symptoms. Laboratory data showed elevated lactate and creatine kinase levels. Brain magnetic resonance imaging (MRI) found a high signal intensity lesion in the left occipital-temporal-parietal lobe on diffusion-weighted imaging (DWI). Magnetic resonance angiography (MRA) revealed reversible vasoconstriction of the middle cerebral arteries and superficial temporal arteries. A muscle biopsy suggested minor muscle damage. A genetic study revealed a mitochondrial DNA A3243G mutation. Conclusion: Elderly onset of MELAS is rare and easily misdiagnosed as an ischemic stroke. MELAS with the onset of stroke-like episodes should be considered in adult or elderly patients with imaging findings that are atypical for cerebral infarction. The use of multimodal MRI in the clinical diagnosis of MELAS could be extremely beneficial.

Linear structural features of Wilson's disease and its correlation with neurological symptoms.

To measure the linear structure of the brain in patients with Wilson's disease (WD) and analyze its correlation with neurological symptoms. A total of 174 patients diagnosed with WD were enrolled. According to the type of clinical presentation, the patients with WD were divided into two groups: neurological (NWD) and hepatic (HWD). Sixty healthy volunteers were assigned to a control group. All patients with WD and healthy controls underwent brain magnetic resonance imaging (MRI). The severity of the neurological symptoms was assessed using the Burke Fahn Marsden Movement subscale (BFM-M). Linear brain measurements were performed using T1-weighted MRI scans of all the patients, and the correlation between these linear indices and BFM-M score was investigated. The Huckman index, third ventricle width, and sulcus width of the NWD group were significantly higher than those of the HWD and control groups (P < .05). The frontal horn index, ventricular index, and lateral ventricular body width index of the NWD group were significantly lower than those of the HWD and control groups (P < .05). The Huckman index and third ventricle width of the HWD group were higher than those of the control group (P < .05), whereas the body width index of the lateral ventricle was lower than that of the control group (P < .05). The BFM-M score correlated with the Huckman index (r = 0.29, P < .05), third ventricle width (r = 0.426, P < .001), and lateral ventricular body width index (r = -0.19, P < .05). This study demonstrated significant changes in the linear structure of patients with WD. Linear brain measurement analysis could be used as a potential method to assess the severity of neurological symptoms in WD.

A patient with hereditary transthyretin amyloidosis involving multiple cranial nerves due to a rare p.(Phe84Ser) variant.

We report a 30-year-old man involving gastrointestinal symptoms, vitreous opacity, and multiple cranial neuropathies. Transthyretin-related hereditary amyloidosis genetic testing revealed a rare c.251T > C variant p.(Phe84Ser). Only four cases with this variant have been reported before.

Distinguishing between the complications of Wilson disease-related cirrhosis and HBV-related cirrhosis.

OBJECTIVE: Complications affect the outcome of patients with cirrhosis. The favorable prognosis of patients with Wilson disease (WD)-related cirrhosis suggests that its complications differ from those of hepatitis B virus (HBV) infection-related cirrhosis. We aimed to delineate the differences in complications between WD-related and HBV-related cirrhosis. METHODS: The electronic-medical data from patients with WD-related and HBV-related cirrhosis were extracted and analyzed. RESULTS: In total, 211 patients with WD-related cirrhosis and 374 patients with HBV-related cirrhosis were enrolled. Most patients with WD progressed to cirrhosis <10 years after disease onset, whereas those with HBV infection often progressed after >10 years. Patients with WD-related cirrhosis had a markedly lower prevalence of ascites (8.5% vs. 38.5%), gastroesophageal varices/variceal bleeding (13.3% vs. 47.6%), renal impairment (0 vs. 7.6%) and primary liver cancer (0 vs. 39.3%; all p < .001) than those with HBV-related cirrhosis. After adjustment for potential confounders, patients with WD-related cirrhosis carried a lower risk of varices/variceal bleeding. CONCLUSIONS: Although patients with WD progressed to cirrhosis much faster, the prevalence of complications from WD-related cirrhosis was low. Patients with WD-related cirrhosis were less likely to develop gastroesophageal varices/variceal bleeding than those with HBV-related cirrhosis.

Persistence with medical treatment for Wilson disease in China based on a single center's survey research.

BACKGROUND: Wilson's disease (WD) is one of the few hereditary diseases that can be successfully treated with medicines. We conduct this survey research to assess treatment persistence among patients with WD and try to identify what factors affect the treatment persistence. METHODS: We employed WeChat which is the most popular social software in China to carry out this anonymous questionnaire research. The questionnaire included medication adherence scale. We also collected available medical records related to demographic and clinical characteristics. All the patients were divided into group of persistence with drug treatment (PDT) and nonpersistence with drug treatment (n-PDT). RESULTS: We collected 242 qualified questionnaires. Only 66.5% of patients were PDT during the mean 12.6 years of follow-up. In PDT group, better outcomes were observed: improvement (78.3%) and no change (16.1%) versus those in n-PDT (55.6%; and 28.4%, respectively). In PDT group, only nine patients deteriorated (6.8%) in comparison with 13 patients in n-PDT (16.0%). The adverse events (AEs) in PDT group were significantly less than those in n-PDT group. There were no significant differences in clinical type, gender, age, education level, and family knowledge about WD between the two groups. There were significant differences in AEs and family position toward treatment. CONCLUSION: Medication Adherence of Chinese WD patients was low. One third of the patients (33.5%) were unable to PDT, and it had an important negative effect on clinical outcome. AEs and family support had an important impact on treatment persistence.

Giant "heart appearance-like sign" on MRI in bilateral ponto-medullary junction infraction: case report.

BACKGROUND: Bilateral medial medullary infarction (MMI) is uncommon and bilateral medial pons infarction (MPI) is even rarer. "Heart appearance" on magnetic resonance imaging (MRI) is a characteristic presentation of bilateral medial medullary infarction (MMI). CASE PRESENTATION: We present 67-year-old Chinese diabetic and hypertensive female patient affected with "heart appearance-like" infarction in bilateral ponto-medullary junction on MRI. Abnormal signal was observed in the bilateral ponto-medullary junction on T1, T2, fluid-attenuated inversion recovery and apparent diffusion coefficient (ADC). The whole brain digital subtraction angiography (DSA) showed the basilar artery and vertebral artery remained intact. Therefore, we speculated that the bilateral ponto-medullary junction infarction might be caused by the deep perforating branch of the basilar artery. CONCLUSIONS: As far as we know, the "heart appearance-like" infraction in bilateral ponto-medullary junction was not reported. Our case also suggests that bilateral ischemic infraction involvement of the medulla and pon is possible even in the context of an intact basilar artery.

Overexpression of PRR11 promotes tumorigenic capability and is associated with progression in esophageal squamous cell carcinoma.

INTRODUCTION: Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies of gastrointestinal tract in the world, and the long-term prognosis for ESCC patients still remains dismal due to the lack of effective early diagnosis biomarkers. MATERIALS AND METHODS: Western blot and immunochemistry were used to determine the expression of PRR11 in 201 clinicopathologically characterized ESCC specimens. The effects of PRR11 on stem cell-like traits and tumorigenicity were examined by tumor sphere formation assay and SP assays in vitro and by a tumorigenesis model in vivo. The mechanism by which PRR11 mediated Wnt/ß-catenin signaling was explored using luciferase reporter, immuno-chemistry, and real time-PCR (RT-PCR) assays. RESULTS: We found that PRR11 was markedly upregulated, at the level of both transcription and translation, in ESCC cell lines as compared with normal esophageal epithelial cells (NECCs). Immunohistochemical analysis showed that 69.2% paraffin-embedded archival ESCC specimens exhibited high levels of PRR11 expression, and multivariate analysis revealed that PRR11 upregulation might be an independent prognostic indicator for the survival of patients with ESCC. Furthermore, overexpression of PRR11 dramatically enhanced, whereas inhibition of PRR11 reduced the capability of cancer stem cell (CSC)-like phenotypes and tumorigenicity of ESCC cells both in vitro and in vivo. Mechanically, we demonstrated PRR11-enhanced tumorigenicity of ESCC cells via activating Wnt/ß-catenin signaling, and PRR11 expression is found to be significantly correlated with ß-catenin nuclear location in ESCC. CONCLUSION: Our findings suggest that the PRR11 might represent a novel and valuable prognostic marker for ESCC progression and play a role during the development and progression of this malignancy.

Characteristics of neurological Wilson's disease with corpus callosum abnormalities.

BACKGROUND: Wilson's disease (WD) is an autosomal recessive disease of impaired copper metabolism. Previous study demonstrated that WD with corpus callosum abnormalities (WD-CCA) was limited to the posterior part (splenium). This study aimed to compare clinical features between WD-CCA and WD without corpus callosum abnormalities (WD-no-CCA). METHODS: Forty-one WD patients who had markedly neurological dysfunctions were included in this study. We retrospectively reviewed clinical, biochemical characteristics and MRI findings in the 41 WD patients. All patients were assessed using the Unified Wilson's Disease Rating Scale. RESULTS: Nine patients had corpus callosum abnormalities, 4 of 9 patients had abnormal signal in the genu and splenium, 5 of 9 patients had abnormal signal only in the splenium. WD-CCA had longer course (9.9 ± 4.0 years vs. 3.4 ± 3.6 years, p<0.01), more severe neurological dysfunctions (37.6 vs. 65.9, p<0.01) and higher psychiatric symptoms scores (11.2 vs. 22.5, p<0.01) than WD-no-CCA. The MRI findings indicated that WD-CCA had higher ratio than WD-no-CCA in globus pallidus (88.9% vs. 43.8%, p = 0.024) and thalamus (100% vs. 59.4%, p = 0.038). The index of liver function and copper metabolism had no significant in WD-CCA and WD-no-CCA patients. CONCLUSION: Our findings indicate Wilson's disease can involve the posterior as well as the anterior part of CC and patients with CC involvement had more extensive brain lesions, more severe neurological dysfunctions and psychiatric symptoms.

TRIM31 promotes glioma proliferation and invasion through activating NF-κB pathway.

BACKGROUND: Glioma is the most lethal primary brain tumor, the survival rate still isn't improved in the past decades. It's essential to study the regulatory mechanism of glioma progression, hoping to find new therapy targets or methods. The family of tripartite motif (TRIM) containing proteins are E3 ubiquitination ligases, which play critical role in various tumor progression. METHODS: Cell proliferation and invasion were analyzed by colony formation assay, soft agar growth assay, BrdU incorporation assay and transwell invasion assay. Luciferase reporter analysis was used to analyze NF-κB pathway activity. RESULTS: We found TRIM31 was upregulated in glioma cells and tissues, its overexpression significantly promoted glioma cell proliferation and invasion, while its knockdown significantly inhibited glioma cell proliferation and invasion. Mechanism analysis found TRIM31 promoted NF-κB pathway activity and increased its targets expression. NF-κB inhibition reversed the phenotype caused by TRIM31, confirming TRIM31 promoted glioma progression through activating NF-κB pathway. Using clinical specimens found TRIM31 expression was positively correlative with NF-κB activity. CONCLUSION: This study found TRIM31 promoted glioma proliferation and invasion through activating NF-κB activity.

Correlation of gene polymorphisms of CD36 and ApoE with susceptibility of Alzheimer disease: A case-control study.

This research was aimed to explore correlation of gene polymorphisms of CD36 and ApoE with susceptibility of Alzheimer disease (AD).This study was a case-control study. Two hundred eleven AD hospitalized patients were selected as the AD group and 241 subjects were selected as the control group. PCR-RFLP was used to detect three loci (rs7755, rs3211956, and rs10499859) of CD36 gene and ApoE genotype. Chi-square test and univariate nonconditional logistic regression analysis were used to calculate the odds ratio (OR) and 95% confidence interval (95% CI). The haplotypes were constructed using SHEsis online software and the correlation between haplotypes and AD was analyzed. Meanwhile, differences of 3 alleles of ApoE and 6 genotypes (E2/E2, E2/E3, E2/E4, E3/E3, E3/E4, E4/E4) were compared between AD and control groups.The frequencies of rs7755 genotype (χ = 10.780, P = .005) and allele (χ = 10.549, P = .001) were statistically different between 2 groups. The genotype frequency of rs3211956 was statistically different between AD and control groups (χ = 10.119, P = .006). For the rs7755 locus, GG genotype (OR: 2.013, 95% CI: 1.098-3.699) was an independent risk factor for AD compared with AA genotype. In the dominant model, the risk to develop AD in AG/GG genotype was 1.686 times higher than AA genotype. For the rs3211956 locus, compared with TT genotype, GT genotype (OR: 0.536, 95% CI: 0.340-0.846) was a protective factor for AD after adjusting various physiological and biochemical factors. In the dominant model, the risk of GT/GG genotype to develop AD was reduced by 41.6%. For ApoE gene, the distribution differences of E2/E3 (χ = 9.216, P = .002), E3/E4 (χ = 7.728, P = .005), and E4/E4 had statistical significance between the 2 groups. The frequencies of allele E2 (χ = 9.359, P = .002) and E4 (χ = 13.995, P < .001) were statistically significant between AD and control groups.The rs7755 and rs3211956 loci polymorphisms of CD36 gene and genotype E2/E3, E3/E4, E4/E4 of ApoE gene, and E2 and E4 alleles were statistically related with AD.

Wnt5a Promotes Cortical Neuron Survival by Inhibiting Cell-Cycle Activation.

ß-Amyloid protein (Aß) is thought to cause neuronal loss in Alzheimer's disease (AD). Aß treatment promotes the re-activation of a mitotic cycle and induces rapid apoptotic death of neurons. However, the signaling pathways mediating cell-cycle activation during neuron apoptosis have not been determined. We find that Wnt5a acts as a mediator of cortical neuron survival, and Aß42 promotes cortical neuron apoptosis by downregulating the expression of Wnt5a. Cell-cycle activation is mediated by the reduced inhibitory effect of Wnt5a in Aß42 treated cortical neurons. Furthermore, Wnt5a signals through the non-canonical Wnt/Ca2+ pathway to suppress cyclin D1 expression and negatively regulate neuronal cell-cycle activation in a cell-autonomous manner. Together, aberrant downregulation of Wnt5a signaling is a crucial step during Aß42 induced cortical neuron apoptosis and might contribute to AD-related neurodegeneration.

[The Correlation between Blood Uric Acid and Goldstein Grading in Hepatolenticular Degeneration Patients with Different Chinese Medical Syndrome Types].

OBJECTIVE: To observe blood uric acid levels and Goldstein grading, as well as their correlation in Wilson's disease (WD) patients with different Chinese medical syndrome types. METHODS: Totally 906 WD patients in line with inclusive criteria were assigned to 6 groups, i.e., the heart spirit confused by phlegm group (HSCP, 26 cases), the phlegm-fire disturbing heart group (PFDH, 90 cases), the retention of damp-heat group (RDH, 113 cases), deficiency of qi and blood group (DQB, 168 cases), the deficiency of Gan-yin and Shen-yin group (DGYSY, 327 cases), the deficiency of Gan and Shen group (DGS, 182 cases) due to different Chinese medical syndrome types. Recruited were another 160 healthy subjects having similar ages and diet structures, who came for medical examinations, as the healthy control group. Venous blood was collected from the medial cubital vein of each-patient on an empty stomach in early mornings to detect blood uric acid levels. Results Blood uric acid levels were lower in each syndrome type group than in the healthy control group (146.08 +/- 67.24 micromol/L in the HSCP group; 157.08 +/- 69.77 micromol/L in the PFDH group; 162.58 +/- 97.72 micromol/L in the RDH group; 156.20 +/- 62.63 micromol/L in the DQB group; 161.83 +/- 111.23 micromol/L in the DGYSY group; 194.41 +/- 90.01 micromol/L in the DGS group; 242.39 +/- 87.55 micromol/L in the healthy control group, P < 0.01). Blood uric acid levels were higher in the DGYSY group than in the other 5 syndrome groups (P < 0.01). Correlation analyses between Goldstein grading and blood uric acid showed that, along with increased Goldstein grade (that was aggravating disease conditions), WD patients' blood uric acid levels decreased (P < 0.01). CONCLUSIONS: WD patient's blood uric acid levels decreased more. Blood uric acid levels and Goldstein grading were different in various Chinese medical syndrome types. Blood uric acid levels had certain value in assessing the severity of WD.

Identification and characterization of a novel splice-site mutation in the Wilson disease gene.

This study aimed to identify aberrant transcripts of the new splice-site mutation c.3244-2A>C in the Wilson disease (WD) gene (ATPase, Cu++ transporting, beta polypeptide, ATP7B) and discuss its genotype and clinical phenotype. DNA and RNA were extracted from peripheral blood lymphocytes, amplified by polymerase chain reaction (PCR) and nested reverse transcription PCR (RT-nested PCR) to characterize the aberrant transcripts. RT-nested PCR product sequencing comparison showed that c.3244-2A>C splice-site mutation caused aberrant transcripts and formatted a new splice acceptor. Patient carrying the splice-site mutation c.3244-2A>C presented early onset age, severe clinical manifestations, and poor prognosis. WD patients with the splice-site mutation show severe clinical manifestations, indicating that aberrant transcripts have important implications for WD phenotype.

Mutation analysis of 73 southern Chinese Wilson's disease patients: identification of 10 novel mutations and its clinical correlation.

This study was designed to investigate the molecular basis and the correlation between genotype and phenotype in the southern Chinese patients with Wilson's disease (WD). Genotypes of the ATP7B gene in 73 WD patients were examined by denaturing high-performance liquid chromatography (DHPLC) and DNA sequencing. A total of 38 different disease-causing mutations were identified, including 10 novel mutations: missense mutations (p.Gln707Arg, p.Cys1079Phe, p.Gly1149Glu, p.Ser855Tyr, p.Ala874Pro and p.Ser921Arg), nonsense mutation (p.Arg1228Stop), splice-site mutations (2121+3A>T and 3244-2A>G) and frameshift mutation (1875_1876insAATT). We found that a pair of siblings carried the same genotype but different clinical type, and two patients were found to have three mutations. In addition, we compared the clinical data for p.Arg778Leu homozygotes and compound heterozygotes. Our research has enriched the mutation spectrum of the ATP7B gene in the Chinese population and can serve as the basis for genetic counseling and clinical/prenatal diagnosis to prevent WD in China.

Super-high-dose methylprednisolone does not improve efficacy or induce glucocorticoid resistance in experimental allergic encephalomyelitis.

OBJECTIVE: To investigate whether a super-high dose (SHD) of methylprednisolone (MP) improves its efficacy or induces glucocorticoid (GC) resistance, and to explore the potential mechanisms of GC resistance in experimental allergic encephalomyelitis (EAE). METHODS: The therapeutic effects of SHD and low-dose MP were evaluated in EAE by analyzing clinical scores, pathological changes and cytokine production. Immunohistochemistry and RT-PCR were used to investigate the expression of GC receptor (GR) isoforms and splicing factor SRp30c. RESULTS: Both MP doses had similar therapeutic effects. The ratio of GRα to GRß was positively correlated with clinical score changes. However, there was no difference in the GRα/GRß ratio between SHD and low-dose MP groups. SRp30c mRNA was correlated with GRß expression. CONCLUSION: This study indicates that the GRα/GRß ratio is associated with GC sensitivity, and SRp30c may play an important role in promoting alternative splicing of GR pre-mRNA to generate GRß in EAE rats. Compared with low-dose MP, SHD MP does not improve efficacy or induce GC resistance.

[Study on relationship between Arg778Leu/Gln gene mutation spot in ATP7B and TCM syndrome type in Chinese patients with Wilson disease].

OBJECTIVE: To investigate the relationship between Arg778Leu/Gln gene mutation spot in ATP7B and TCM Syndrome type in Chinese patients with Wilson disease (WD). METHODS: Exon 8 of ATP7B of 90 WD patients and 30 healthy controls were amplified by PCR and analysed by restriction enzyme Msp I, the TCM Syndrome type of the patients was differentiated at the same time. RESULTS: In the 90 WD patients, 34 with Arg778Leu/Gln of exon 8 were detected, among them 20 cases belonged to the TCM Syndrome type of endogenous Liver-Wind agitation. CONCLUSION: Onset age of WD patients with Arg778Leu/Gln mutation is later than that without this mutation. Arg778Leu/Gln mutation might be related to the TCM Syndrome type of endogenous Liver-Wind agitation.
