The c.815G>A (p.R272H) alteration is located in exon 11 (coding exon 11) of the PSTPIP2 gene. This alteration results from a G to A substitution at nucleotide position 815, causing the arginine (R) at amino acid position 272 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
