Sometimes: Some cases are due to a mutation carried by the mother. Most are due to spontaneous mutations or epigenetic events in the fertilized egg. So, the risk of Angelman may be inherited, but the disease may be genetic or due to epigenetic factors. It is one of the most complex genetic mechanisms yet discovered, and a clinical geneticist must analyze whether other family members are at up to 50% risk

Neither: Angelman's syndrome doesn't follow simple mendelian genetics. Rather, it's due to de novo single genetic mutations, translocational errors, chromosomal abnormalities, or more commonly epi-genetic mutations such as changes in dna methylation.

Angelman syndrome: Angelman syndrome is a genetic cause of developmental delay and neurological problems. Affected kids have"flat heads, jerky movements, protruding tongues, and bouts of laughter." infants appear normal at birth, but often have feeding problems in the first months of life and exhibit noticeable developmental delays by 6 to 12 months.

Does the doctor need to do to tests to be sure if the diagnosis is angelman syndrome?
1 doctor answer • 3 doctors weighed in

Dr. Scott McLean answered
Clinical Genetics 35 years experience
Genetic tests help: But tests alone will not confirm the diagnosis in 1 out of 10 children with angelman syndrome. Common signs are very delayed development, speech impairment, and trouble with coordination. A specific and complex checklist is the standard way to establish the diagnosis. Anywhere from 1 to 6 genetic tests are used to confirm the diagnosis and tell us if the condition might happen again in the family.

There is a large mouth with a protruding tongue, hyperactivity is common. Gait is wide based and ataxic with tremulous movements. Pubertal development is delayed, adult height is less than the 3rd percentile. It is associated with a deletion on chromosome 15.
