Genes affected

SIK1 (HGNC:11142): (salt inducible kinase 1) This gene encodes a serine/threonine protein kinase that contains a ubiquitin-associated (UBA) domain. The encoded protein is a member of the adenosine monophosphate-activated kinase (AMPK) subfamily of kinases that play a role in conserved signal transduction pathways. A mutation in this gene is associated with early infantile epileptic encephalopathy 30. [provided by RefSeq, Nov 2016]

This sequence change replaces alanine with glycine at codon 513 of the SIK1 protein (p.Ala513Gly). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and glycine. 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. ClinVar contains an entry for this variant (Variation ID: 938594). This variant has been observed in individual(s) with clinical features of SIK1-related conditions (Invitae). This variant is present in population databases (rs200402559, ExAC 0.002%). -
