Genes affected

MYO1C (HGNC:7597): (myosin IC) This gene encodes a member of the unconventional myosin protein family, which are actin-based molecular motors. The protein is found in the cytoplasm, and one isoform with a unique N-terminus is also found in the nucleus. The nuclear isoform associates with RNA polymerase I and II and functions in transcription initiation. The mouse ortholog of this protein also functions in intracellular vesicle transport to the plasma membrane. Multiple transcript variants encoding different isoforms have been found for this gene. The related gene myosin IE has been referred to as myosin IC in the literature, but it is a distinct locus on chromosome 19. [provided by RefSeq, Jul 2008]

Ambry Genetics

Sep 26, 2023

The c.2955G>C (p.Q985H) alteration is located in exon 30 (coding exon 29) of the MYO1C gene. This alteration results from a G to C substitution at nucleotide position 2955, causing the glutamine (Q) at amino acid position 985 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
