Mutation size and age at onset in Huntington's disease.
The mutation responsible for Huntington's disease is a polymorphic (CAG)n repeat sequence which is expanded on affected chromosomes. The number of repeat units observed on 229 affected chromosomes varied from 27 to 102, while the control chromosomes showed a range of 7 to 34 repeats. There was a highly significant relationship between the size of the expanded region and age at onset, larger mut...
متن کاملRELATIONSHIP BETWEEN KNEE MALALIGNMENT AND QANGLE WITH AGE AT ONSET OF DISEASE IN 260 CHONDROMALACIA PATELLA PATIENTS
Background: Chondromalacia patella is the most common cause of mechanical knee pain in young women. Q angle and knee alignment are important clinical parameters for biomechanics of the patellofemoral joint. Objective: To identify the prevalence of knee malalignment and to find out if there is a correlation between knee mal alignment and Q angle with age at onset of disease. Methods: All pa...
متن کاملAge at onset and Parkinson disease phenotype.
OBJECTIVE To explore clinical phenotype and characteristics of Parkinson disease (PD) at different ages at onset in recently diagnosed patients with untreated PD. METHODS We have analyzed baseline data from the Parkinson's Progression Markers Initiative database. Four hundred twenty-two patients with a diagnosis of PD confirmed by DaTSCAN imaging were divided into 4 groups according to age at...
متن کاملAPOE and other loci affect age-at-onset in Alzheimer's disease families with PS2 mutation.
Several kindreds of Volga German (VG) ancestry have a single PS2 mutation that causes an autosomal dominant form of Alzheimer's disease (AD). These families show a wide range in age-at-onset, which suggests the existence of modifying factors other than the PS2 mutation. To examine evidence for a genetic basis of variation in onset age, we performed a Bayesian oligogenic segregation and linkage ...
متن کاملAge at onset in Huntington's disease and methylation at D4S95.
Age at onset in Huntington's disease (HD) is variable and is influenced by parental sex, paternal age, and genetic background. Several recent models have tried to explain this variable expressivity by invoking parental imprinting and related aspects of epigenetic inheritance. Some of these mechanisms may result in variable DNA methylation at or near the HD gene. We show here that methylation at...
