Genes affected

STK4 (HGNC:11408): (serine/threonine kinase 4) The protein encoded by this gene is a cytoplasmic kinase that is structurally similar to the yeast Ste20p kinase, which acts upstream of the stress-induced mitogen-activated protein kinase cascade. The encoded protein can phosphorylate myelin basic protein and undergoes autophosphorylation. A caspase-cleaved fragment of the encoded protein has been shown to be capable of phosphorylating histone H2B. The particular phosphorylation catalyzed by this protein has been correlated with apoptosis, and it's possible that this protein induces the chromatin condensation observed in this process.

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 STK4 protein function. This variant has not been reported in the literature in individuals affected with STK4-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.01%). This sequence change replaces proline, which is neutral and non-polar, with leucine, which is neutral and non-polar, at codon 10 of the STK4 protein (p.Pro10Leu). -
