Any autosomal recessive non-syndromic intellectual disability in which the cause of the disease is a mutation in the FMN2 gene.
Features include always present findings: Global developmental delay and Intellectual disability; and very common findings: Poor speech and Delayed speech and language development. 7 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Brain and nerves | 5 | Poor speech, Delayed speech and language development, Focal impaired awareness seizure |
Muscles | 1 | Generalized hypotonia |
Heart and blood vessels | 1 | Mitral valve prolapse |
Age of onset: adolescence.
FMN2 encodes formin 2 (1,722 aa). Actin-binding protein that is involved in actin cytoskeleton assembly and reorganization. Acts as an actin nucleation factor and promotes assembly of actin filaments together with SPIRE1 and SPIRE2. Highest expression in Brain Frontal Cortex BA9 (16.7 TPM) and Brain Cortex (14.5 TPM).
Intellectual disability, autosomal recessive 47 is associated with mutations in the FMN2 gene on chromosome 1.
FMN2 is classified as a druggable target with score 0.0.
Genetic testing for FMN2 is available. Testing is considered confirmatory for diagnosis.
