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

Verdict is Pathogenic. Variant got 12 ACMG points.

• PVS1: Splicing variant, LoF is a know mechanism of disease, No cryptic splice site detected. Exon removal results in frameshift change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 2-111898787-TGGCGTAGAGGTGAGTGCGCCC-T is Pathogenic according to our data. Variant chr2-111898787-TGGCGTAGAGGTGAGTGCGCCC-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1333384.Status of the report is criteria_provided_single_submitter, 1 stars.

Canonical splice site: predicted to alter splicing and result in a loss or disruption of normal protein function through protein truncation. Multiple pathogenic variants are reported in the predicted truncated region (PVS1_VS).It is not observed in the gnomAD v2.1.1 dataset (PM2_M). Therefore, this variant is classified as likely pathogenic according to the recommendation of ACMG/AMP guideline. -
