Causes defects of genes on chromosome 3 and 18. Seckel syndrome , or microcephalic primordial dwarfism (also known as bird-headed dwarfism , Harper's syndrome , Virchow–Seckel dwarfism and bird-headed dwarf of Seckel [ 1 ] ) is an extremely rare congenital nanosomic disorder.
Mental retardation and microcephaly with pontine and cerebellar hypoplasia (MICPCH) – also known as mental retardation, X-linked, syndromic, Najm type (MRXSNA); X-linked intellectual deficit, Najm type; intellectual developmental disorder, X-linked, syndromic, Najm type; X-linked intellectual disability–microcephaly–pontocerebellar hypoplasia syndrome; and by variations of these terms ...
Congenital microcephaly has also been attributed to serine deficiencies that cause defects in two known enzymes: 3-phosphogycerate dehydrogenase and 3-phosphoserine phosphatase, leading to severe neurological abnormalities [16] Like familial achalasia, microcephaly has an autosomal recessive predisposition.

Microcephaly is a characteristic in which the circumference of the head is smaller than normal due to improper development of the brain. It is caused by genetic disorders, infections, radiation, medications or alcohol use during pregnancy. Defects in the growth of the cerebral cortex lead to many of the features associated with microcephaly. [4]
