Genes affected

MYO10 (HGNC:7593): (myosin X) This gene encodes a member of the myosin superfamily. The protein represents an unconventional myosin; it should not be confused with the conventional non-muscle myosin-10 (MYH10). Unconventional myosins contain the basic domains of conventional myosins and are further distinguished from class members by their tail domains. This gene functions as an actin-based molecular motor and plays a role in integration of F-actin and microtubule cytoskeletons during meiosis. [provided by RefSeq, Dec 2011]

The c.5818A>C (p.M1940L) alteration is located in exon 39 (coding exon 39) of the MYO10 gene. This alteration results from a A to C substitution at nucleotide position 5818, causing the methionine (M) at amino acid position 1940 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
