The c.1232G>A (p.R411H) alteration is located in exon 3 (coding exon 3) of the CSPG5 gene. This alteration results from a G to A substitution at nucleotide position 1232, causing the arginine (R) at amino acid position 411 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
