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

Classification made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PP2
Missense variant in the NIPBL gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 86 curated pathogenic missense variants (we use a threshold of 10). The gene has 69 curated benign missense variants. Gene score misZ: 5.5737 (above the threshold of 3.09). Trascript score misZ: 6.6817 (above the threshold of 3.09). GenCC associations: The gene is linked to Cornelia de Lange syndrome, Cornelia de Lange syndrome 1.
BP4
Computational evidence support a benign effect (MetaRNN=0.027493864).
BP6
Variant 5-36986083-A-G is Benign according to our data. Variant chr5-36986083-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 159066.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=2, Benign=2, Uncertain_significance=1}.
BS1
Variant frequency is greater than expected in population eas. gnomad4 allele frequency = 0.000223 (34/152268) while in subpopulation EAS AF= 0.000964 (5/5188). AF 95% confidence interval is 0.000379. There are 0 homozygotes in gnomad4. There are 16 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 34 AD gene.
