Ambry Genetics

Oct 18, 2021

The c.583A>C (p.M195L) alteration is located in exon 5 (coding exon 5) of the CATSPER4 gene. This alteration results from a A to C substitution at nucleotide position 583, causing the methionine (M) at amino acid position 195 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
