Genes affected

GSDME (HGNC:2810): (gasdermin E) Hearing impairment is a heterogeneous condition with over 40 loci described. The protein encoded by this gene is expressed in fetal cochlea, however, its function is not known. Nonsyndromic hearing impairment is associated with a mutation in this gene. Three transcript variants encoding two different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.826T>C (p.S276P) alteration is located in exon 6 (coding exon 5) of the DFNA5 gene. This alteration results from a T to C substitution at nucleotide position 826, causing the serine (S) at amino acid position 276 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.

Jul 16, 2014

Laboratory for Molecular Medicine, Mass General Brigham Personalized Medicine

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

Ser276Pro in exon 6 of DFNA5: This variant is not expected to have clinical sign ificance due to a lack of conservation across species, including mammals. Of not e, dolphin, killer whale, horse, cow, Egyptian jerboa, white rhinoceros, and pan da have a proline (Pro) at this position despite high nearby amino acid conserva tion. In addition, computational prediction tools do not suggest a high likelih ood of impact to the protein.
