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]

The c.2420G>A (p.R807H) alteration is located in exon 2 (coding exon 1) of the SLITRK6 gene. This alteration results from a G to A substitution at nucleotide position 2420, causing the arginine (R) at amino acid position 807 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
