Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2024The c.691C>T (p.R231W) 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 691, causing the arginine (R) at amino acid position 231 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
not provided Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingGeneDxJan 20, 2022Has not been previously published as pathogenic or benign to our knowledge; In silico analysis supports that this missense variant has a deleterious effect on protein structure/function -
