The c.3869G>A (p.R1290Q) alteration is located in exon 25 (coding exon 24) of the PITPNM2 gene. This alteration results from a G to A substitution at nucleotide position 3869, causing the arginine (R) at amino acid position 1290 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
