FRA12A DIP2B

Disease ID
FRA12A
Gene ID
DIP2B

Disease

Name
Intellectual developmental disorder, FRA12A type
Inheritance
Autosomal dominant
Description
...impaired intellectual development with or without other anomalies has been described in patients with over 40% of cells expressing FRA12A1 .
Prevalence
Appears to occur in those of European ancestry/ethnicity1 .
Age of OnsetYears0  3
Age of Onset Details
Typical: 0-1 (small sample size)2 . Range: 0-33 .

Locus

Details
Repeat ranges reflect affected and unaffected individuals from a cohort study of 70 controls (6-23 repeats), unaffected carriers representing the intermediate alleles (139-206), and affected individuals (273-306)4 .
Mechanism
LoF
Hypermethylation leading to decreased expression, although unmethylated expansion leads to increased expression1,5 .
