Description

The p.S1651A variant (also known as c.4951T>G), located in coding exon 26 of the NOTCH1 gene, results from a T to G substitution at nucleotide position 4951. The serine at codon 1651 is replaced by alanine, 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.
