Collection Method: clinical testing

The c.637C>G (p.L213V) alteration is located in exon 8 (coding exon 8) of the CATSPERD gene. This alteration results from a C to G substitution at nucleotide position 637, causing the leucine (L) at amino acid position 213 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
