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.

The c.2902G>A (p.E968K) 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 2902, causing the glutamic acid (E) at amino acid position 968 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
