Jul 14, 2021

The c.403A>C (p.M135L) alteration is located in exon 3 (coding exon 3) of the CATSPER3 gene. This alteration results from a A to C substitution at nucleotide position 403, causing the methionine (M) at amino acid position 135 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
