Genes affected
DIP2B (HGNC:29284): (disco interacting protein 2 homolog B) This gene encodes a member of the disco-interacting protein homolog 2 protein family. The encoded protein contains a binding site for the transcriptional regulator DNA methyltransferase 1 associated protein 1 as well as AMP-binding sites. The presence of these sites suggests that the encoded protein may participate in DNA methylation. This gene is located near a folate-sensitive fragile site, and CGG-repeat expansion in the promoter of this gene which affects transcription has been detected in individuals containing this fragile site on chromosome 12.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 2 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DIP2B. . Gene score misZ 3.1809 (greater than the threshold 3.09). Trascript score misZ 4.0584 (greater than threshold 3.09). GenCC has associacion of gene with intellectual disability, FRA12A type.
BP4
Computational evidence support a benign effect (MetaRNN=0.42143673).
