Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.200G>T (p.C67F) alteration is located in exon 2 (coding exon 2) of the SNAI3 gene. This alteration results from a G to T substitution at nucleotide position 200, causing the cysteine (C) at amino acid position 67 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
