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.

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The Ser556Phe variant in MYO1A has not been previously reported in individuals w ith hearing loss and was absent from large population studies. Computational pr ediction tools and conservation analyses do not provide strong support for or ag ainst an impact to the protein. In summary, the clinical significance of the Ser 556Phe variant is uncertain. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.1667C>T (p.S556F) alteration is located in exon 17 (coding exon 16) of the MYO1A gene. This alteration results from a C to T substitution at nucleotide position 1667, causing the serine (S) at amino acid position 556 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

Sep 19, 2018

GeneDx

Significance:Likely benign

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -
