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]

The c.35C>T (p.S12F) alteration is located in exon 1 (coding exon 1) of the TIAF1 gene. This alteration results from a C to T substitution at nucleotide position 35, causing the serine (S) at amino acid position 12 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
