Genes affected

MYO18A (HGNC:31104): (myosin XVIIIA) The protein encoded by this gene can bind GOLPH3, linking the Golgi to the cytoskeleton and influencing Golgi membrane trafficking. The encoded protein is also part of a complex that assembles lamellar actomyosin bundles and may be required for cell migration. [provided by RefSeq, Oct 2016]

Ambry Genetics

Nov 17, 2022

The c.6098C>T (p.P2033L) alteration is located in exon 42 (coding exon 41) of the MYO18A gene. This alteration results from a C to T substitution at nucleotide position 6098, causing the proline (P) at amino acid position 2033 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
