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 GeneticsAug 27, 2024The c.589G>A (p.D197N) alteration is located in exon 7 (coding exon 7) of the STK32B gene. This alteration results from a G to A substitution at nucleotide position 589, causing the aspartic acid (D) at amino acid position 197 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
