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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 10, 2024The c.197G>A (p.R66Q) alteration is located in exon 3 (coding exon 3) of the STK32B gene. This alteration results from a G to A substitution at nucleotide position 197, causing the arginine (R) at amino acid position 66 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
