The c.944A>G (p.Q315R) alteration is located in exon 2 (coding exon 2) of the CSPG5 gene. This alteration results from a A to G substitution at nucleotide position 944, causing the glutamine (Q) at amino acid position 315 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
