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.

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 01, 2023The c.11G>C (p.R4P) alteration is located in exon 1 (coding exon 1) of the DIP2B gene. This alteration results from a G to C substitution at nucleotide position 11, causing the arginine (R) at amino acid position 4 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
