Frequently Asked Questions

What is a 2p deletion?

She is an absolute joy and blessing and I can’t imagine my life without her! A 2p deletion means that the cells of the body are missing a part of one of the 46 chromosomes, in this case part of chromosome 2. For healthy development, chromosomes should contain just the right amount of genetic material (DNA) – not too much and not too little.

What are the two types of deletion?

One type of deletion is called terminal. There is one breakpoint and a part of the chromosome from the breakpoint to the end of the arm is missing. Another type of deletion is called interstitial. There are two breakpoints on the same arm that have rejoined and the part between them is missing.

What is a deletion on a chromosome?

Deletion on a chromosome. In genetics, a deletion (also called gene deletion, deficiency, or deletion mutation) (sign: Δ) is a mutation (a genetic aberration) in which a part of a chromosome or a sequence of DNA is lost during DNA replication. Any number of nucleotides can be deleted, from a single base to an entire piece of chromosome.

What is chromosome 2q deletion?

Summary Summary. Chromosome 2q deletion is a chromosome abnormality that occurs when there is a missing copy of the genetic material located on the long arm (q) of chromosome 2. The severity of the condition and the signs and symptoms depend on the size and location of the deletion and which genes are involved.
