Genes affected
MYO1A (HGNC:7595): (myosin IA) This gene encodes a member of the myosin superfamily. The protein represents an unconventional myosin; it should not be confused with the conventional skeletal muscle myosin-1 (MYH1). Unconventional myosins contain the basic domains characteristic of conventional myosins and are further distinguished from class members by their tail domains. They function as actin-based molecular motors. Mutations in this gene have been associated with autosomal dominant deafness. Alternatively spliced variants have been found for this gene. [provided by RefSeq, Dec 2011]
TAC3 (HGNC:11521): (tachykinin precursor 3) This gene encodes a member of the tachykinin family of secreted neuropeptides. The encoded preproprotein is proteolytically processed to generate the mature peptide, which is primarily expressed in the central and peripheral nervous systems and functions as a neurotransmitter. This peptide is the ligand for the neurokinin-3 receptor. This protein is also expressed in the outer syncytiotrophoblast of the placenta and may be associated with pregnancy-induced hypertension and pre-eclampsia. Mutations in this gene are associated with normosmic hypogonadotropic hypogonadism. Alternative splicing results in multiple transcript variants, at least one of which encodes an isoform that is proteolytically processed. [provided by RefSeq, Feb 2016]

Variant classified as Uncertain Significance - Favor Benign. The Lys1031Glu vari ant in MYO1A has been previously reported in one individual with hearing loss at tributed to two pathogenic variants in GJB2 (Shearer 2013). It has also been ide ntified in 0.02% (2/8600) of European American chromosomes by the NHLBI Exome Se quencing Project (http://evs.gs.washington.edu; dbSNP rs371613423). Computationa l analyses (amino acid biochemical properties, conservation, AlignGVGD, PolyPhen 2, SIFT) suggest this variant may impact the protein, though this information is not predictive enough to determine pathogenicity. In summary, the clinical sign ificance of this variant cannot be determined with certainty at this time; howev er, based upon the identification of this variant in an individual with an alter nate cause of hearing loss (reported in Shearer 2013), we would lean towards a m ore likely benign role. -
