The c.950G>A (p.R317Q) alteration is located in exon 10 (coding exon 7) of the GPBP1L1 gene. This alteration results from a G to A substitution at nucleotide position 950, causing the arginine (R) at amino acid position 317 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
