Genes affected

SLITRK3 (HGNC:23501): (SLIT and NTRK like family member 3) This gene encodes a member of the Slitrk family of structurally related transmembrane proteins that are involved in controlling neurite outgrowth. The encoded protein contains two leucine-rich repeat (LRR) domains and a C-terminal domain that is partially similar to Trk neurotrophin receptor protein. Enhanced expression of this gene was found in tissue from several different types of tumors. Alternative splicing results in multiple transcript variants, all encoding the same protein.

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.3484065).

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2819G>A (p.G940E) alteration is located in exon 2 (coding exon 1) of the SLITRK3 gene. This alteration results from a G to A substitution at nucleotide position 2819, causing the glycine (G) at amino acid position 940 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
