Genes affected

SLITRK5 (HGNC:20295): (SLIT and NTRK like family member 5) Members of the SLITRK family, such as SLITRK5, are integral membrane proteins with 2 N-terminal leucine-rich repeat (LRR) domains similar to those of SLIT proteins (see SLIT1; MIM 603742). Most SLITRKs, including SLITRK5, also have C-terminal regions that share homology with neurotrophin receptors (see NTRK1; MIM 191315). SLITRKs are expressed predominantly in neural tissues and have neurite-modulating activity (Aruga et al., 2003 [PubMed 14557068]).[supplied by OMIM, Mar 2008]

Collection Method: clinical testing

The c.122T>C (p.I41T) alteration is located in exon 2 (coding exon 1) of the SLITRK5 gene. This alteration results from a T to C substitution at nucleotide position 122, causing the isoleucine (I) at amino acid position 41 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
