Ambry Genetics

Feb 06, 2024

The c.1390C>T (p.R464W) alteration is located in exon 4 (coding exon 4) of the CSPG5 gene. This alteration results from a C to T substitution at nucleotide position 1390, causing the arginine (R) at amino acid position 464 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
