Ambry Genetics

Jan 03, 2024

The c.205G>A (p.V69M) alteration is located in exon 3 (coding exon 2) of the KHDC1 gene. This alteration results from a G to A substitution at nucleotide position 205, causing the valine (V) at amino acid position 69 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
