Seckel syndrome

Seckel syndrome A rare inherited form of dwarfism and growth delay. Other symptoms and features associated with Seckel syndrome include an abnormally small head (microcephaly); varying degrees of mental retardation; and/or unusual characteristic facial features including “beak-like” protrusion of the nose. The syndrome is inherited in an autosomal recessive manner and can be due to mutations in several different genes. Also known as bird-headed dwarfism, microcephalic primordial dwarfism, nanocephalic dwarfism, and Seckel-type dwarfism. See also dwarfism.
