Ambry Genetics

Feb 01, 2023

The c.188C>T (p.A63V) alteration is located in exon 2 (coding exon 2) of the HN1 gene. This alteration results from a C to T substitution at nucleotide position 188, causing the alanine (A) at amino acid position 63 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
