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]

The c.2333C>T (p.T778M) alteration is located in exon 14 (coding exon 13) of the SIK1 gene. This alteration results from a C to T substitution at nucleotide position 2333, causing the threonine (T) at amino acid position 778 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
