Genes affected

STK32B (HGNC:14217): (serine/threonine kinase 32B) This gene encodes a serine-threonine protein kinase. Serine-threonine kinases transfer phosphate molecules to the oxygen atoms of serine and threonine. A genomic deletion affecting this gene has been associated with Ellis-van Creveld syndrome, an autosomal recessive skeletal dysplasia. Alternative splicing results in multiple transcript variants.

Apr 20, 2023

The c.170A>G (p.Q57R) alteration is located in exon 3 (coding exon 3) of the STK32B gene. This alteration results from a A to G substitution at nucleotide position 170, causing the glutamine (Q) at amino acid position 57 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
