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.

The c.56A>C (p.N19T) alteration is located in exon 2 (coding exon 2) of the STK32B gene. This alteration results from a A to C substitution at nucleotide position 56, causing the asparagine (N) at amino acid position 19 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
