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 GeneticsSep 21, 2023The c.377C>T (p.P126L) 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 377, causing the proline (P) at amino acid position 126 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
