Labcorp Genetics (formerly Invitae), Labcorp RCV001973844 SCV002260167 uncertain significance Developmental and epileptic encephalopathy, 30 2021-07-26 criteria provided, single submitter clinical testing Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is not expected to disrupt SIK1 protein function. 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. This variant has not been reported in the literature in individuals with SIK1-related conditions. This variant is present in population databases (rs745825829, ExAC 0.003%). This sequence change replaces threonine with alanine at codon 231 of the SIK1 protein (p.Thr231Ala). The threonine residue is moderately conserved and there is a small physicochemical difference between threonine and alanine.
Ambry Genetics RCV002573421 SCV003633587 likely benign Inborn genetic diseases 2022-06-06 criteria provided, single submitter clinical testing This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity.
