Variant summary

Our verdict is Uncertain significance. The variant received 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_152744.4(SDK1):​c.92C>G​(p.Ser31Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000692 in 144,458 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 15/22 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S31Y) has been classified as Uncertain significance.

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]

SDK1-AS1 (HGNC:40883): (SDK1 antisense RNA 1)

ACMG classification

Our verdict: Uncertain_significance. The variant received 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.14640173).
