• 16p11.2 Deletion Syndrome

• The proximal 16p11. 2 microdeletion syndrome is a chromosomal anomaly characterized by developmental and language delays, mild intellectual disability, social impairments (autism spectrum disorders), mild variable dysmorphism and predisposition to obesity. Synonym(s): Proximal del(16)(p11.
• Rarechemo

• 1p36 Deletion Syndrome

• 1p36 deletion syndrome is a disorder that typically causes intellectual disabilities. Most affected individuals do not speak or speak only a few words. They may have temper tantrums, bite themselves, or exhibit other behaviour problems.

• Rarechemo

• 22q11.2 Microduplications

• Microduplications, or submicroscopic duplications, are chromosomal duplications that are too small to be detected by light microscopy using conventional cytogenetics methods. Specialized testing is needed to identify these duplications.
• Rarechemo

• 3p Deletion Syndrome

• The 3p deletion syndrome is a rare disorder caused by deletions of different sizes in the 3p25-pter region. It is characterized by growth retardation, developmental delay, mental retardation, dysmorphism, microcephaly, and ptosis. The phenotype of individuals with deletions varies from normal to severe.
• medlineplus

• 8p23.1 Deletion Syndrome

• 8p23. 1 deletion involves a partial deletion of the short arm of chromosome 8 characterized by low birth weight, postnatal growth deficiency, mild intellectual deficit, hyperactivity, craniofacial abnormalities, and congenital heart defects. Synonym(s): Del(8)(p23.
