Genes affected

CTCF (HGNC:13723): (CCCTC-binding factor) This gene is a member of the BORIS + CTCF gene family and encodes a transcriptional regulator protein with 11 highly conserved zinc finger (ZF) domains. This nuclear protein is able to use different combinations of the ZF domains to bind different DNA target sequences and proteins. Depending upon the context of the site, the protein can bind a histone acetyltransferase (HAT)-containing complex and function as a transcriptional activator or bind a histone deacetylase (HDAC)-containing complex and function as a transcriptional repressor. If the protein is bound to a transcriptional insulator element, it can block communication between enhancers and upstream promoters, thereby regulating imprinted expression. Mutations in this gene have been associated with invasive breast cancers, prostate cancers, and Wilms' tumors. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -9 ACMG points.

PP2

Missense variant in the CTCF gene, where missense mutations are typically associated with disease (based on misZ statistic). The gene has 29 curated pathogenic missense variants (we use a threshold of 10). The gene has 7 curated benign missense variants. Gene score misZ: 4.4399 (above the threshold of 3.09). Trascript score misZ: 4.8366 (above the threshold of 3.09). GenCC associations: The gene is linked to intellectual disability, autosomal dominant 40, syndromic intellectual disability, intellectual disability-feeding difficulties-developmental delay-microcephaly syndrome.

BP4

Computational evidence support a benign effect (MetaRNN=0.034507275).

BP6

Variant 16-67610963-A-G is Benign according to our data. Variant chr16-67610963-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 1701292.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAd4 at 6 AD gene.
