Genes affected

SDK1 (HGNC:19307): (sidekick cell adhesion molecule 1) The protein encoded by this gene is a member of the immunoglobulin superfamily. The protein contains six immunoglobulin-like domains and thirteen fibronectin type III domains. Fibronectin type III domains are present in both extracellular and intracellular proteins and tandem repeats are known to contain binding sites for DNA, heparin and the cell surface. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2016]

The c.116C>T (p.S39L) alteration is located in exon 1 (coding exon 1) of the SDK1 gene. This alteration results from a C to T substitution at nucleotide position 116, causing the serine (S) at amino acid position 39 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
