Ambry Genetics

Apr 15, 2024

The c.737C>T (p.A246V) alteration is located in exon 5 (coding exon 5) of the POU2AF1 gene. This alteration results from a C to T substitution at nucleotide position 737, causing the alanine (A) at amino acid position 246 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
