Genes affected

SLITRK6 (HGNC:23503): (SLIT and NTRK like family member 6) This gene encodes a member of the SLITRK protein family. Members of this family are integral membrane proteins that are characterized by two N-terminal leucine-rich repeat (LRR) domains and a C-terminal region that shares homology with trk neurotrophin receptors. This protein functions as a regulator of neurite outgrowth required for normal hearing and vision. Mutations in this gene are a cause of myopia and deafness. [provided by RefSeq, Dec 2014]

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

This sequence change replaces lysine, which is basic and polar, with glutamic acid, which is acidic and polar, at codon 817 of the SLITRK6 protein (p.Lys817Glu). This variant is present in population databases (rs375486226, gnomAD 0.04%). This variant has not been reported in the literature in individuals affected with SLITRK6-related conditions. ClinVar contains an entry for this variant (Variation ID: 1492137). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.2449A>G (p.K817E) alteration is located in exon 2 (coding exon 1) of the SLITRK6 gene. This alteration results from a A to G substitution at nucleotide position 2449, causing the lysine (K) at amino acid position 817 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
