A case of classical Vohwinkel syndrome caused by the mutation p.N54H in the GJB2 gene / 中华皮肤科杂志

Objective:To detect gene mutations in 1 patient with Vohwinkel syndrome who presented with palmoplantar keratoderma, pseudo-ainhum and deafness.Methods:Clinical data were collected from the proband, and a genetic test was performed to identify mutation sites.Results:Clinical manifestations of the proband were consistent with classical Vohwinkel syndrome. The genetic test revealed a heterozygous mutation c.160A>C (p.N54H) in the GJB2 gene, which was not detected in her parents or healthy controls.Conclusion:The heterozygous mutation c.160A>C (p.N54H) in the GJB2 gene was first identified in a patient with classical Vohwinkel syndrome, and there were overlaps in mutation sites between classical Vohwinkel syndrome and palmoplantar keratoderma with deafness.
