Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change replaces serine, which is neutral and polar, with threonine, which is neutral and polar, at codon 72 of the DRC1 protein (p.Ser72Thr). This variant is present in population databases (rs149398412, gnomAD 0.09%). This variant has not been reported in the literature in individuals affected with DRC1-related conditions. ClinVar contains an entry for this variant (Variation ID: 454986). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance:Uncertain significance

Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.215G>C (p.S72T) alteration is located in exon 2 (coding exon 2) of the DRC1 gene. This alteration results from a G to C substitution at nucleotide position 215, causing the serine (S) at amino acid position 72 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
