Ambry Genetics

Dec 06, 2022

The c.46C>G (p.L16V) alteration is located in exon 1 (coding exon 1) of the CYHR1 gene. This alteration results from a C to G substitution at nucleotide position 46, causing the leucine (L) at amino acid position 16 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
