What happens if you have 7 chromosomes?
Abnormalities involving the inheritance of chromosome 7 can cause Russell-Silver syndrome, a rare condition characterized by slow growth, distinctive facial features, delayed development, speech and language problems, and learning disabilities.

Features that often occur in people with chromosome 6q deletion include developmental delay , intellectual disability , and distinctive facial features. Most cases are not inherited , but people can pass the deletion on to their children. Treatment is based on the signs and symptoms present in each person.
What is chromosome 6 deletion syndrome?
Chromosome 6 Ring is a rare disorder in which there is loss (deletion) of chromosomal material from both ends of the 6th chromosome and joining of the ends to form a ring. Associated symptoms and findings may vary greatly, depending upon the amount and location of lost chromosomal material and other factors.

What does chromosome 6 look like?
Chromosome 6 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 6 spans more than 170 million base pairs (the building material of DNA) and represents between 5.5 and 6% of the total DNA in cells.
How many genes does chromosome 6 have?
Chromosome 6 likely contains 1,000 to 1,100 genes that provide instructions for making proteins.
What chromosome is autism located on?
An extra copy of a stretch of genes on chromosome 22 may contribute to autism, according to the first study to carefully characterize a large group of individuals who carry this duplication1. The doubling can also lead to medical complications, such as vision or heart problems. The region, called 22q11.
What is a William syndrome?

What causes Cdls?
What causes Cornelia de Lange syndrome? Cornelia de Lange syndrome is genetic condition that is caused by mutations in at least five genes (NIPBL, RAD21, SMC3, HDAC8, and SMC1A). The severity of the condition can vary greatly depending on the type of mutation and which gene is affected.
