Is William syndrome hereditary?
Williams syndrome is usually caused by a random genetic mutation, or error, in chromosome 7. This means that most people with Williams syndrome have not inherited the condition from a parent. People with Williams syndrome have a 50% chance of passing the condition on to each of their offspring.
Why do people have Williams syndrome?
Williams syndrome is caused by the deletion of genetic material from a specific region of chromosome 7. The deleted region includes 26 to 28 genes, and researchers believe that a loss of several of these genes probably contributes to the characteristic features of this disorder.
What meiotic event causes Williams syndrome?
Mechanisms whereby chromosomes paired during meiosis may undergo unequal crossover resulting in Williams syndrome have typically been thought to result from an unequal overlap of repetitive Alu sequences flanking the region, resulting in a type of misalignment of the chromosomal regions during a crossover event.
Is Williams syndrome a form of autism?
Autism spectrum disorders (ASD) and Williams syndrome (WS) both are neurodevelopmental disorders, each with a unique social phenotypic pattern.
