Ambry Genetics

Mar 31, 2023

The c.646G>A (p.V216I) alteration is located in exon 7 (coding exon 7) of the KLHDC1 gene. This alteration results from a G to A substitution at nucleotide position 646, causing the valine (V) at amino acid position 216 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
