Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 30, 2022The c.652C>T (p.R218C) alteration is located in exon 3 (coding exon 3) of the SDR9C7 gene. This alteration results from a C to T substitution at nucleotide position 652, causing the arginine (R) at amino acid position 218 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
