Case report: Heterogeneous mutations of SOX10 gene in a Chinese infant with Waardenburg syndrome type 4C
Abstract
A 5-month-old patient presented with grayish-blue iris bilaterally, skin and mucosal pigmentation loss, Hirschsprung's disease, full-blown growth retardation, and sensorineural deafness. The patient's whole exon gene sequencing revealed a spontaneous heterozygous code-shifting mutation in the SOX10 gene: c.803del:p.K268Sfs*18. The parents of the child were wild-type, and the site of the mutation is novel.
