The c.3426G>T (p.Q1142H) alteration is located in exon 18 (coding exon 18) of the PHLPP2 gene. This alteration results from a G to T substitution at nucleotide position 3426, causing the glutamine (Q) at amino acid position 1142 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
