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 17, 2022The c.503C>T (p.A168V) alteration is located in exon 6 (coding exon 6) of the STK32B gene. This alteration results from a C to T substitution at nucleotide position 503, causing the alanine (A) at amino acid position 168 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
