Variant summary

Our verdict is Uncertain significance. Variant got 1 ACMG points: 1P and 0B. PP3

The NM_173354.5(SIK1):​c.1828C>T​(p.Arg610Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. In-silico tool predicts a pathogenic 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. R610H) has been classified as Uncertain significance.

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]

Developmental and epileptic encephalopathy, 30 Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingInvitaeDec 11, 2023This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 610 of the SIK1 protein (p.Arg610Cys). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This variant has not been reported in the literature in individuals affected with SIK1-related conditions. ClinVar contains an entry for this variant (Variation ID: 521524). 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 with a negative predictive value of 95%. 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. -
