300005.0011; RETT SYNDROME |
| Identified Mutation |
ARG294TER; DeBona et al. [Europ. J. Hum. Genet. 8: 325-330 (2000)] identified an 880C-T transition in the MECP2 gene, leading to an arg294-to-ter (R294X) nonsense mutation in four unrelated patients with Rett Syndrome, thus indicating that this represents a hot spot. |
| Remarks |
Clinically affected; symptoms began at age 6 months; significantly abnormal EEG; breath holding; constipation, growth and mental retardation; limited purposeful hand use; nonverbal; repetitive hand motions; agitation; scoliosis; seizures; some tremors and teeth grinding; small hands and feet; severely microcephalic; gait apraxia and ataxia; donor subject is heterozygous for an 880C>T transition in the MECP2 gene resulting in an arg294-to-ter [ARG294TER (R294X)] nonsense mutation. |
