Collection Method: clinical testing

The c.490C>T (p.R164C) alteration is located in exon 7 (coding exon 7) of the CATSPERD gene. This alteration results from a C to T substitution at nucleotide position 490, causing the arginine (R) at amino acid position 164 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
