ABSTRACT
Objective:
To summarize the clinical manifestations of a case of combined oxidative phosphorylation deficiency 28 (COXPD-28) caused by the mutations of the SLC25A26 gene, thus providing references for the diagnosis and genetic counseling of the disease.Methods:
Clinical data of a case of COXPD-28 treated in the Third Affiliated Hospital of Zhengzhou University in October 2020 were retrospectively analyzed.In addition, The retrieval words " Combined oxidative phosphorylation deficiency 28, SLC25A26 gene" were used to search domestic and foreign databases.The clinical characteristics of combined phosphorylation deficiency 28 and the variation characteristics of SLC25A26 gene were summarized.Results:
(1) A female patient full-term delivered after 30 min presented with groaning breath was admitted.Her main manifestations included pale complexion, groaning breathing, metabolic acidosis, and high lactate and pyruvate levels.Symptomatic support treatment like anti-infection and assisted ventilation were given, but her condition gradually worsened and died of respiratory and circulatory failure on the day of admission.The child was compound heterozygous mutation of SLC25A26 gene, the terminating mutation of exon 5 c. 403G>T caused the protein change to p. E135, and the non-synonymous mutation of exon 4 c. 212A>G caused the protein change to p. Y71C.(2) A total of 3 cases of COXPD-28 were searched in online databases, and no cases were reported in China.Through literature review, clinical features of COXPD-28 mainly included respiratory and circulatory fai-lure, elevations of lactate and pyruvate, and reductions of complexes Ⅰ, Ⅲ and Ⅳ in muscle biopsy.Two types of mutations in the SLC25A26 gene were detected, including 3 cases of missense mutations and 1 case of splicing mutation.Conclusions:
COXPD-28 is an autosomal recessive genetic disease involving multiple systems and mitochondrial dysfunction.Mutations in the SLC25A26 gene is the pathological cause of COXPD-28.
