"Description": "FRA12A is a rare, folate-sensitive chromosomal fragile site on chromosome 12 associated with intellectual developmental disorder, FRA12A type. The DIP2B CGG repeat expansion causes this folate-sensitive site and is associated with a broad phenotypic range, including intellectual disability, ataxia/movement disorder, and epilepsy; cardiovascular associations have also been reported but were not scored and are noted for completeness. For this curation, the neurodevelopmental and neurologic presentations (intellectual disability, ataxia/movement disorder, and epilepsy) were lumped as a single phenotypic spectrum, which supports the current score. If these phenotypes are treated as distinct entities, the evidence strength and resulting score may differ. Patients across multiple independent families and cohorts provide inheritance and functional support. Mechanistically, repeat expansions are associated with promoter hypermethylation, altered regulatory activity, and changes in DIP2B expression. Case-control studies report enrichment of DIP2B expansions in ataxia cohorts (OR = 2.8) and cardiovascular disease populations (OR = 2.7), and computational analyses support biological relevance through conservation and a predicted interaction with the DMAP1 methylation complex.",

This included healthy probands with highly expanded alleles, and probands with various neurological and non neurological presentations. There was no clear association between size of expanded alleles and presence of neurological disorders, which contributes to the disputed classification of this locus.",
