Genes affected
FAM136A (HGNC:25911): (family with sequence similarity 136 member A) This gene encodes a mitochondrially localized protein that is highly conserved across species. The gene is expressed in a variety of tissues including human lymphoblast cells and rat neurosensorial epithelium of the cristaampullaris. A mutation in this gene has been associated with familial Meniere's disease, a chronic disorder of the inner ear. Several pseudogenes of this gene are found on other chromosomes. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Aug 2016]

The c.287C>A (p.A96D) alteration is located in exon 3 (coding exon 3) of the FAM136A gene. This alteration results from a C to A substitution at nucleotide position 287, causing the alanine (A) at amino acid position 96 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
