Genes affected

RBPJ (HGNC:5724): (recombination signal binding protein for immunoglobulin kappa J region) The protein encoded by this gene is a transcriptional regulator important in the Notch signaling pathway. The encoded protein acts as a repressor when not bound to Notch proteins and an activator when bound to Notch proteins. It is thought to function by recruiting chromatin remodeling complexes containing histone deacetylase or histone acetylase proteins to Notch signaling pathway genes. Several transcript variants encoding different isoforms have been found for this gene, and several pseudogenes of this gene exist on chromosome 9. [provided by RefSeq, Oct 2013]

ACMG classification

Verdict is Pathogenic. Variant got 11 ACMG points.

• PM1: In a strand (size 7) in uniprot entity SUH_HUMAN there are 5 pathogenic changes around while only 0 benign (100%) in NM_015874.6
• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), RBPJ. . Gene score misZ 3.5749 (greater than the threshold 3.09). Trascript score misZ 3.8981 (greater than threshold 3.09). GenCC has associacion of gene with Adams-Oliver syndrome 3, Adams-Oliver syndrome.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.953
• PP5: Variant 4-26415476-T-G is Pathogenic according to our data. Variant chr4-26415476-T-G is described in ClinVar as [Likely_pathogenic]. Clinvar id is 523587.Status of the report is criteria_provided_single_submitter, 1 stars.
