Genes affected

MERTK (HGNC:7027): (MER proto-oncogene, tyrosine kinase) This gene is a member of the MER/AXL/TYRO3 receptor kinase family and encodes a transmembrane protein with two fibronectin type-III domains, two Ig-like C2-type (immunoglobulin-like) domains, and one tyrosine kinase domain. Mutations in this gene have been associated with disruption of the retinal pigment epithelium (RPE) phagocytosis pathway and onset of autosomal recessive retinitis pigmentosa (RP).

This sequence change creates a premature translational stop signal (p.Arg651*) in the MERTK gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in MERTK are known to be pathogenic (PMID: 24265693, 29659094). This variant is present in population databases (rs119489105, gnomAD 0.01%). This premature translational stop signal has been observed in individual(s) with clinical features of inherited retinal dystrophies (PMID: 11062461, 20300561, 25097241). ClinVar contains an entry for this variant (Variation ID: 5402). Algorithms developed to predict the effect of sequence changes on RNA splicing suggest that this variant may disrupt the consensus splice site. For these reasons, this variant has been classified as Pathogenic. -

The p.Arg651Ter variant in MERTK was identified in an individual with Retinitis pigmentosa, via a collaborative study between the Broad Institute's Center for Mendelian Genomics and the Pierce lab (https://oculargenomics.meei.harvard.edu/labs/pierce-lab/lab-members/). Through a review of available evidence we were able to apply the following criteria: PVS1, PM2, PM3-P. Based on this evidence we have classified this variant as Pathogenic. If you have any questions about the classification please reach out to the Pierce Lab. -
