Collection Method: clinical testing

The c.214G>A (p.G72S) alteration is located in exon 4 (coding exon 4) of the POU2AF1 gene. This alteration results from a G to A substitution at nucleotide position 214, causing the glycine (G) at amino acid position 72 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
