ClinVar Variants & Pathogenicity by Type

Statistics based on transcript NM_203458.6. Only rare variants are included.

We include only reliable ClinVar variants with their consequences to MANE Select, MANE Plus Clinical transcripts, or transcripts with TSL equal to 1. Click a count to filter the variants table below.

Slight differences between displayed counts and ClinVar may occur due to a different transcript/consequence chosen by our variant effect predictor, or because we classify Benign/Likely benign as Likely benign and Pathogenic/Likely pathogenic as Likely pathogenic.

Function
FUNCTION: Human-specific protein that promotes neural progenitor proliferation and evolutionary expansion of the brain neocortex by regulating the Notch signaling pathway (PubMed:29856954, PubMed:29856955, PubMed:29561261). Able to promote neural progenitor self-renewal, possibly by down-regulating neuronal differentiation genes, thereby delaying the differentiation of neuronal progenitors and leading to an overall final increase in neuronal production (PubMed:29856954). Acts by enhancing the Notch signaling pathway via two different mechanisms that probably work in parallel to reach the same effect (PubMed:29856954). Enhances Notch signaling pathway in a non-cell-autonomous manner via direct interaction with NOTCH2 (PubMed:29856954). Also promotes Notch signaling pathway in a cell-autonomous manner through inhibition of cis DLL1-NOTCH2 interactions, which promotes neuronal differentiation (By similarity). {ECO:0000250|UniProtKB:P0DPK3, ECO:0000269|PubMed:29561261, ECO:0000269|PubMed:29856954, ECO:0000269|PubMed:29856955}.;
Disease
DISEASE: Note=Defects in NOTCH2NLA may be a cause of chromosome 1q21.1 deletion/duplication syndrome (PubMed:29856954). Deletions of NOTCH2NL (NOTCH2NLA, NOTCH2NLB and/or NOTCH2NLC) are present in patients affected by microcephaly, whereas macrocephaly is observed in patients with NOTCH2NL duplications (PubMed:29856954). {ECO:0000269|PubMed:29856954}.;
