NameProfessorSubjectDateAngelman SyndromeIntroductionAngelman syndrome , a neuro agenttic complaint , was first delineated by Dr chafe Angelman in 1965 through intensive examination on the arrest on children . The inactivation of a component for ubiquitin-protein ligase orUBE3A which is similarly fixed in chromosome 15 causes mutation resulting to Angelman syndrome (Niemitz and Feinberg 599 . This mutation triggers delayed push skills victimization , seizures , jerky-puppet stance , cognitive skills impairments , paroxysmal laughter , style defects , stick out tongue and prognathism . In the course of ripening and development , the UBE3A gene is transmitted by the father into the payoff while the maternal allele shapes the brain (Niemitz and Feinberg 599 . Meanwhile , the issue of the pioneer researches conducted by Dr . Angelman on the mysterious happy-puppet syndrome has led to the assignment of chromosomal aberrations on 15q11-13 as the prime cause of the disease (Pelc , Cheron and Dan 578 .

As progresses , the factors that speed 15q11-13 chromosomal aberrations were successfully traced that led to the trait of the Angelman syndrome from Pader-Willi syndrome . Specifically , the typeface of the UBE3A gene in the brain was named as the major perpetrator for the occurrence of the disease . Physiologically , lone(prenominal) maternal allele is typically expressed in distinct regions of the brain . The absence seizure of UBE 3A gene leads to the 15q11-13 deletion from ! motherly inherited chromosome , paternal UPD , UBE3A gene mutation , and imprinting concenter mutation (Pelc , Cheron and Dan 578 . Since UBE3A gene was identify the phenotypic may slacken off cues on the underpinning genetic instrument of the disease .
