Ambry Genetics

Apr 07, 2022

The c.158G>A (p.S53N) alteration is located in exon 2 (coding exon 1) of the DIRAS2 gene. This alteration results from a G to A substitution at nucleotide position 158, causing the serine (S) at amino acid position 53 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
