The c.334C>G (p.Q112E) alteration is located in exon 5 (coding exon 5) of the PSTPIP2 gene. This alteration results from a C to G substitution at nucleotide position 334, causing the glutamine (Q) at amino acid position 112 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
