| HP:0000007 | Autosomal recessive inheritance | "A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in homozygotes. In the context of medical genetics, autosomal recessive disorders manifest in homozygotes (with two copies of the mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele)."

Thus, ambylopia can result from strabismus, anisometropia, or high hypermetropia in there is a failure to form a focused image in one or both eyes." [HPO:curators] |
