Ambry Genetics

Mar 17, 2023

The c.629C>T (p.A210V) alteration is located in exon 6 (coding exon 6) of the GRTP1 gene. This alteration results from a C to T substitution at nucleotide position 629, causing the alanine (A) at amino acid position 210 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
