Abstract:
Objective:To explore the clinical features and pathogenic mechanisms of a special syndrome with congenital sensorineural hearing loss, albinism, heterochromia iridis, nystagmus and myelin dysplasia.Methods:Detailed medical history, systematic audiology tests, ophthalmic and neurological examinations were carried out to analyze the clinical features of the child, and further molecular genetic tests including chromosome karyotype analysis, and deafness gene screening were conducted.Results:A new de novo heterozygous mutation (c.336G>T/p.Met112Ile) was detected in the child, while both his parents were demonstrated to be wild-type and symptom free. The analysis of clinical features indicated the diagnosis of PCW syndrome. Conclusion:This study identified a new mutation of SOX10 gene, which enriched the mutation spectrum of this gene. And the analysis of clinical characteristics of this patient also expanded the phenotype of this gene. This study provided a reference for clinical diagnosis and genetic diagnosis of PCW syndrome.
