Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 06, 2021The c.1381C>T (p.R461W) alteration is located in exon 9 (coding exon 9) of the DCT gene. This alteration results from a C to T substitution at nucleotide position 1381, causing the arginine (R) at amino acid position 461 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
