Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 21, 2023The c.508C>T (p.R170W) alteration is located in exon 4 (coding exon 4) of the RSAD1 gene. This alteration results from a C to T substitution at nucleotide position 508, causing the arginine (R) at amino acid position 170 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
