Genes affected

NIPBL (HGNC:28862): (NIPBL cohesin loading factor) This gene encodes the homolog of the Drosophila melanogaster Nipped-B gene product and fungal Scc2-type sister chromatid cohesion proteins. The Drosophila protein facilitates enhancer-promoter communication of remote enhancers and plays a role in developmental regulation. It is also homologous to a family of chromosomal adherins with broad roles in sister chromatid cohesion, chromosome condensation, and DNA repair. The human protein has a bipartite nuclear targeting sequence and a putative HEAT repeat. Condensins, cohesins and other complexes with chromosome-related functions also contain HEAT repeats. Mutations in this gene result in Cornelia de Lange syndrome, a disorder characterized by dysmorphic facial features, growth delay, limb reduction defects, and cognitive disability. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Benign. Variant got -10 ACMG points.

• PM1: In a compositionally_biased_region Basic and acidic residues (size 28) in uniprot entity NIPBL_HUMAN there are 6 pathogenic changes around while only 1 benign (86%) in NM_133433.4
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), NIPBL. . Gene score misZ 5.5737 (greater than the threshold 3.09). Trascript score misZ 6.6817 (greater than threshold 3.09). GenCC has associacion of gene with Cornelia de Lange syndrome, Cornelia de Lange syndrome 1.
• BP4: Computational evidence support a benign effect (MetaRNN=0.3262983).
• BP6: Variant 5-36984706-C-G is Benign according to our data. Variant chr5-36984706-C-G is described in ClinVar as [Likely_benign]. Clinvar id is 99922.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS2: High AC in GnomAdExome4 at 14 AD gene.
