No patient was hypopigmented; 1 patient was fair. No clinical difference between the sporadic cases and the sib cases was discerned.
This small region defined seneromu component of the imprinting center involved in Angelman syndrome, i. The parental origin was determined using cytogenetic markers in 13 of the cases, by the pattern of inheritance of RFLPS in 9, and by both techniques in 3. CCCCC ]. In a review of clinical features in 36 children with Angelman syndrome, Robb et al.
Linkage analysis with chromosome 15q markers shows genomic imprinting in familial Angelman syndrome. Most males proved to be fertile, but, perhaps because of the developing obesity, females were often infertile. Most patients between the ages of 2 and 16 years showed at least 8 of the major characteristics of the syndrome bursts of laughter, happy disposition, hyperactivity, micro- and brachycephaly, macrostomia, tongue protrusion, prognathism, widely spaced teeth, puppet-like movements, wide-based gait in addition to mental retardation qngelman absence of speech.
