Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 21, 2022The c.82C>T (p.R28C) alteration is located in exon 1 (coding exon 1) of the CATSPER4 gene. This alteration results from a C to T substitution at nucleotide position 82, causing the arginine (R) at amino acid position 28 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
