ABSTRACT

OBJECTIVES:

This study aims to document the clinical features of patients with COL11A2 mutations and to describe the usefulness of massively parallel sequencing.

METHODS:

One thousand one hundred twenty (1120) Japanese hearing loss patients from 53 ENT departments nationwide participated in this study. Massively parallel sequencing of 63 genes implicated in hearing loss was performed to identify the genetic causes in the Japanese hearing loss patients.

RESULTS:

A novel mutation in COL11A2 (c.3937_3948delCCCCCAGGGCCA) was detected in an affected family, and it was segregated in all hearing loss individuals. The clinical findings of this family were compatible with non-ocular Stickler syndrome. Orofacial features of mid-facial hypoplasia and slowly progressive mild to moderate hearing loss were also presented. Audiological examinations showed favorable auditory performance with hearing aid(s).

CONCLUSION:

This is the first case report of the genetic diagnosis of a non-ocular Stickler syndrome family in the Japanese population. We suggest that it is important to take both genetic analysis data and clinical symptoms into consideration to make an accurate diagnosis.
