Renpenning's syndrome

Renpenning's syndrome is a neurodevelopmental disorder recognised in males intellectual disability, mild growth retardation with examples in the testes and head, and a somewhat short stature. The condition only affects males, starting at birth, and was first described by Hans Renpenning in 1963 after he documented these traits on many children in one family alone.

It was characterized in 1962.

It can be associated with PQBP1.

Characteristics
People with Renpenning's typically begin learning language at an ordinary pace, but by the age of 3–4 they experience a regression in mental and physical development, such as mild low muscle tone resulting in elongated faces and rapid loss in the normal growth of the head (microcephaly). Small testes and short stature are also known to commonly occur.
