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]
SNAI3-AS1 (HGNC:28327): (SNAI3 antisense RNA 1)

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 23, 2024The c.83A>G (p.N28S) alteration is located in exon 2 (coding exon 2) of the SNAI3 gene. This alteration results from a A to G substitution at nucleotide position 83, causing the asparagine (N) at amino acid position 28 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
