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).

Significance:Pathogenic

Review Status:criteria provided, single submitter

Collection Method:clinical testing

This sequence change creates a premature translational stop signal (p.Arg727*) 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 (no rsID available, gnomAD 0.002%). This premature translational stop signal has been observed in individual(s) with clinical features of retinitis pigmentosa (PMID: 28462455). It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 866075). For these reasons, this variant has been classified as Pathogenic. -
