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]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Apr 21, 2023	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. 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. ClinVar contains an entry for this variant (Variation ID: 1197937). This variant has not been reported in the literature in individuals affected with SLITRK6-related conditions. This variant is present in population databases (rs200882739, gnomAD 0.06%). This sequence change replaces tyrosine, which is neutral and polar, with histidine, which is basic and polar, at codon 805 of the SLITRK6 protein (p.Tyr805His). -
Uncertain significance, criteria provided, single submitter	clinical testing	GeneDx	Apr 06, 2020	In silico analysis, which includes protein predictors and evolutionary conservation, supports that this variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge -

The c.2413T>C (p.Y805H) alteration is located in exon 2 (coding exon 1) of the SLITRK6 gene. This alteration results from a T to C substitution at nucleotide position 2413, causing the tyrosine (Y) at amino acid position 805 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

The SLITRK6 c.2413T>C variant is predicted to result in the amino acid substitution p.Tyr805His. This variant has been reported in an individual with hearing loss (El Naofal et al 2023. PubMed ID: 36703223). This variant is reported in 0.060% of alleles in individuals of Latino descent in gnomAD. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
