Variant summary
Our verdict is Likely benign. Variant got -4 ACMG points: 0P and 4B. BP4_Strong
The NM_173354.5(SIK1):c.1471G>A(p.Val491Ile) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V491L) has been classified as Likely benign.

Uncertain significance, criteria provided, single submitter | clinical testing | Invitae | Apr 18, 2023 | ClinVar contains an entry for this variant (Variation ID: 1427786). 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. 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. This variant has not been reported in the literature in individuals affected with SIK1-related conditions. This variant is present in population databases (rs140222760, gnomAD 0.005%). This sequence change replaces valine, which is neutral and non-polar, with isoleucine, which is neutral and non-polar, at codon 491 of the SIK1 protein (p.Val491Ile). - |
