Ambry Genetics

Oct 25, 2022

The c.390G>C (p.E130D) alteration is located in exon 4 (coding exon 4) of the KHDRBS2 gene. This alteration results from a G to C substitution at nucleotide position 390, causing the glutamic acid (E) at amino acid position 130 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
