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]

ACMG classification

Our verdict: Benign. The variant received -10 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.45).
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.454 is higher than 0.05.
