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).

Pathogenic, criteria provided, single submitter	clinical testing	CeGaT Center for Human Genetics Tuebingen	Jun 01, 2018	- -
Pathogenic, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Jul 21, 2020	For these reasons, this variant has been classified as Pathogenic. Loss-of-function variants in MERTK are known to be pathogenic (PMID: 24265693, 29659094). This variant 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). This variant is not present in population databases (ExAC no frequency). 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. -
