Ambry Genetics

Feb 10, 2022

The c.650T>C (p.L217P) alteration is located in exon 7 (coding exon 7) of the KLHDC1 gene. This alteration results from a T to C substitution at nucleotide position 650, causing the leucine (L) at amino acid position 217 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
