Ambry Genetics

Feb 15, 2023

The c.3782C>T (p.A1261V) alteration is located in exon 25 (coding exon 24) of the PITPNM2 gene. This alteration results from a C to T substitution at nucleotide position 3782, causing the alanine (A) at amino acid position 1261 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
