Case report of congenital neutropenia type 4 with glucose-6-phosphatase catalytic subunit 3 (G6PC3) deficiency.

Congenital neutropenia syndromes encompass a group of genetic disorders characterized by persistent neutropenia and recurrent infections inherited in an autosomal recessive, dominant, or X-linked manner. These syndromes arise from mutations in various genes, and one of the significant genes involved is glucose-6-phosphatase catalytic subunit 3 (G6PC3), giving rise to a condition known as Dursun syndrome. As per existing knowledge, a total of 92 cases of Dursun syndrome have been reported globally, including eight cases from Saudi Arabia. Our study identified two additional cases exhibiting neutropenia since the early postnatal period and recurrent admissions due to infections. Additionally, these patients presented with oral ulcers, chronic diarrhea, and anomalies affecting the cardiac and genitourinary systems. The rising incidence of congenital neutropenia on a global scale necessitates heightened vigilance among clinicians to ensure thorough follow-up of patients with neutropenia. This proactive approach can lead to early detection and appropriate management of associated complications, ultimately improving patient outcomes.

Ellis-van Creveld Syndrome 2 With Novel Partial Exon 11 Deletion: A Case From Saudi Arabia.

Ellis-van Creveld syndrome (EVC) is a rare genetic disorder characterized by chondral and ectodermal dysplasia. Clinical features may include polydactyly, growth retardation, short ribs, and heart defects. The exact prevalence is still unclear; however, the Amish community in the United States is the most common community to report this rare disease. Until now, only six cases have been reported in Saudi Arabia so far. This is the first case to be reported in the Jazan region. Jazan covers an area of 11,671 km² and has a population of 1,567,547 at the 2017 census. This region has the highest population density with a high consanguinity marriage rate. We present a case of EVC with typical clinical findings, which was confirmed by homozygous mutation in the EVC2 gene in the region of Jazan, Saudi Arabia. Besides the six cases that were reported from Saudi Arabia, this makes it a total of seven cases. The prenatal findings are considered a good predictor of the disease outcome. More effort is needed in making a national registry of rare disorders to report such cases and provide more awareness among highly consanguinity marriage communities.
