NameProfessorSubjectDateAngelman SyndromeIntroductionAngelman syndrome , a neuro agenttic ailment , was first delineated by Dr chevy Angelman in 1965 through intensive examination on the buy up on children . The inactivation of a component for ubiquitin-protein ligase orUBE3A which is similarly find in chromosome 15 causes mutation resulting to Angelman syndrome (Niemitz and Feinberg 599 . This mutation triggers delayed move skills victimization , seizures , jerky-puppet stance , cognitive skills impairments , paroxysmal laughter , terminology defects , stick out tongue and prognathism . In the course of growth and development , the UBE3A gene is transmitted by the father into the proceeds while the maternal allele shapes the brain (Niemitz and Feinberg 599 . Meanwhile , the return key of the pioneer researches conducte d by Dr . Angelman on the mysterious happy-puppet syndrome has led to the appointment 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 characteristic 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 , however maternal allele is typically expressed in defined regions of the brain . The absence seizur e of UBE3A gene leads to the 15q11-13 deleti! on from maternally inherited chromosome , paternal UPD , UBE3A gene mutation , and imprinting come to mutation (Pelc , Cheron and Dan 578 . Since UBE3A gene was identify the phenotypic may stop cues on the underpinning genetic instrument of the disease .
