Submissions by phenotype

Cardiovascular phenotype Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 15, 2023The p.T1254M variant (also known as c.3761C>T), located in coding exon 23 of the SOS2 gene, results from a C to T substitution at nucleotide position 3761. The threonine at codon 1254 is replaced by methionine, an amino acid with similar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
