Any isolated microphthalmia in which the cause of the disease is a mutation in the MFRP gene.
Features include always present findings: Bone spicule pigmentation of the retina, Nyctalopia, Optic disc drusen, and Scleral thickening and others; and sometimes findings: Photophobia. 14 total HPO annotations.
Organ System | Phenotype Count | Example Features |
|---|---|---|
Eyes | 5 | Optic disc drusen, Cystoid macular edema, Cataract |
Bones and joints | 1 | Bone spicule pigmentation of the retina |
Muscles | 1 | Retinal pigment epithelial atrophy |
MFRP encodes membrane frizzled-related protein (579 aa). May play a role in eye development Highest expression in Brain Hippocampus (0.1 TPM) and Brain Spinal cord cervical c-1 (0.1 TPM).
Isolated microphthalmia 5 is associated with mutations in the MFRP gene on chromosome 11.
MFRP is classified as a druggable target with score 0.0.
Genetic testing for MFRP is available. Testing is considered confirmatory for diagnosis.
