| 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)."

In general, this can refer to neurological diseases but also fractures or other sources of pain that is triggered upon walking. However, in the current context gait disturbance refers to difficulty walking on the basis of a neurological or muscular disease." [HPO:curators] |

In the context of medical genetics, X-linked recessive disorders manifest in males (who have one copy of the X chromosome and are thus hemizygotes), but generally not in female heterozygotes who have one mutant and one normal allele."

| HP:0002069 | Generalized tonic-clonic seizures | "Generalized tonic-clonic seizures are `generalized seizures` (HP:0002197) in which the patient suddenly loses conciousness, the eyes roll back, and the entire body musculature undergoes tonic contractions. In the clonic phase of the seizure, there are rhythmic contractions of the musculature alternating with relaxation of all muscle groups. Loss of sphincter control during the seizure is common. This form of seizure was formerly commonly called grand mal seizure." [HPO:curators] |
