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 Benign. Variant got -13 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BP6: Variant 4-26359946-G-A is Benign according to our data. Variant chr4-26359946-G-A is described in ClinVar as [Benign]. Clinvar id is 444129.Status of the report is no_assertion_criteria_provided, 0 stars. Variant chr4-26359946-G-A is described in Lovd as [Benign].
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.0836 is higher than 0.05.
