Genes affected
RARB (HGNC:9865): (retinoic acid receptor beta) This gene encodes retinoic acid receptor beta, a member of the thyroid-steroid hormone receptor superfamily of nuclear transcriptional regulators. This receptor localizes to the cytoplasm and to subnuclear compartments. It binds retinoic acid, the biologically active form of vitamin A which mediates cellular signalling in embryonic morphogenesis, cell growth and differentiation. It is thought that this protein limits growth of many cell types by regulating gene expression. The gene was first identified in a hepatocellular carcinoma where it flanks a hepatitis B virus integration site. Alternate promoter usage and differential splicing result in multiple transcript variants. [provided by RefSeq, Mar 2014]

ACMG classification

Classification made for transcript

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RARB. . Gene score misZ 2.8661 (greater than the threshold 3.09). Trascript score misZ 3.1257 (greater than threshold 3.09). GenCC has associacion of gene with microphthalmia, syndromic 12, Matthew-Wood syndrome.
PP3
Splicing scoreres supports a deletorius effect: Scorers claiming Pathogenic: dbscSNV1_ADA, dbscSNV1_RF. No scorers claiming Uncertain. Scorers claiming Benign: max_spliceai.
PP5
Variant 3-25501182-G-T is Pathogenic according to our data. Variant chr3-25501182-G-T is described in ClinVar as [Likely_pathogenic]. Clinvar id is 1710325.Status of the report is criteria_provided_single_submitter, 1 stars.
