Ambry Genetics

Oct 27, 2022

The c.725T>C (p.V242A) alteration is located in exon 6 (coding exon 6) of the KHDRBS2 gene. This alteration results from a T to C substitution at nucleotide position 725, causing the valine (V) at amino acid position 242 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
