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.

The c.239C>A (p.S80Y) alteration is located in exon 3 (coding exon 3) of the DIP2B gene. This alteration results from a C to A substitution at nucleotide position 239, causing the serine (S) at amino acid position 80 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
