Types of<unk> include the following: *Terminal<unk> – a<unk> that occurs towards the end of a chromosome. *Intercalary/interstitial<unk> – a<unk> that occurs from the interior of a chromosome. *Microdeletion – a relatively small amount of<unk> (up to 5Mb that could include a dozen genes). Micro-deletion is usually found in children with physical abnormalities. A large amount of<unk> would result in immediate abortion (miscarriage).
