Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 07, 2024The c.13C>T (p.R5C) alteration is located in exon 1 (coding exon 1) of the CATSPER3 gene. This alteration results from a C to T substitution at nucleotide position 13, causing the arginine (R) at amino acid position 5 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
