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).

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.051 fraction of the gene. Cryptic splice site detected, with MaxEntScore 3.1, offset of 33, new splice context is: ctgGTattg. Cryptic site results in inframe change. If cryptic site found is not functional and variant results in exon loss, it results in frameshift change.

PM2

Very rare variant in population databases, with high coverage;

PP5

Variant 2-111997478-T-G is Pathogenic according to our data. Variant chr2-111997478-T-G is described in ClinVar as [Pathogenic]. Clinvar id is 191124.Status of the report is criteria_provided_single_submitter, 1 stars. Variant chr2-111997478-T-G is described in Lovd as [Pathogenic].
