Genes affected
REEP6 (HGNC:30078): (receptor accessory protein 6) The protein encoded by this gene may be involved in the transport of receptors from the endoplasmic reticulum (ER) to the cell surface. The encoded protein may also play a role in regulating ER membrane structure. This gene is required for the proper development of retinal rods and photoreceptors, with defects in this gene being associated with retinitis pigmentosa 77. [provided by RefSeq, May 2017]

This sequence change creates a premature translational stop signal (p.Ala150Profs*2) in the REEP6 gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in REEP6 are known to be pathogenic (PMID: 27889058, 29120066). This variant is not present in population databases (gnomAD no frequency). This premature translational stop signal has been observed in individual(s) with retinitis pigmentosa (PMID: 27889058). ClinVar contains an entry for this variant (Variation ID: 375312). For these reasons, this variant has been classified as Pathogenic. -
