The c.3164A>T (p.H1055L) alteration is located in exon 14 (coding exon 13) of the PIK3R4 gene. This alteration results from a A to T substitution at nucleotide position 3164, causing the histidine (H) at amino acid position 1055 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
