Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.332A>T (p.H111L) alteration is located in exon 2 (coding exon 2) of the SNAI3 gene. This alteration results from a A to T substitution at nucleotide position 332, causing the histidine (H) at amino acid position 111 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
