The c.955C>T (p.R319W) alteration is located in exon 2 (coding exon 2) of the CSPG5 gene. This alteration results from a C to T substitution at nucleotide position 955, causing the arginine (R) at amino acid position 319 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
