Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 01, 2024The c.1042T>C (p.W348R) alteration is located in exon 8 (coding exon 8) of the DSCC1 gene. This alteration results from a T to C substitution at nucleotide position 1042, causing the tryptophan (W) at amino acid position 348 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
