The c.1169G>A (p.R390Q) alteration is located in exon 5 (coding exon 5) of the GPATCH3 gene. This alteration results from a G to A substitution at nucleotide position 1169, causing the arginine (R) at amino acid position 390 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
