Genes affected

SNAI3 (HGNC:18411): (snail family transcriptional repressor 3) SNAI3 is a member of the SNAIL gene family, named for the Drosophila snail gene, which plays roles in mesodermal formation during embryogenesis (Katoh and Katoh, 2003 [PubMed 12579345]).[supplied by OMIM, Apr 2009]

The c.223C>T (p.R75W) alteration is located in exon 2 (coding exon 2) of the SNAI3 gene. This alteration results from a C to T substitution at nucleotide position 223, causing the arginine (R) at amino acid position 75 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
