Seckel syndrome is a rare genetic disorder characterized by growth retardation, severe microcephaly, and intellectual disability. It presents with unique facial features such as a bird-like face, large eyes, beak-like nose, narrow face, and receding lower jaw. Inheritance is autosomal recessive, and some individuals may also have blood abnormalities. Seckel syndrome is a form of microcephalic primordial dwarfism, resulting in a smaller body size from prenatal onset. Individuals with this syndrome exhibit intrauterine growth restriction and postnatal dwarfism, with a distinct facial appearance and intellectual disability.
