| Stimmler syndrome is characterized by the association of microcephaly, low birth weight and severe intellectual deficit with dwarfism, small teeth and diabetes mellitus. Two cases have been described. Biochemical tests reveal the presence of high levels of alanine in the urine and elevated alanine, pyruvate and lactate levels in the blood. |

Structural central nervous system abnormalities (cervical spinal cyst, occipital cranium bifidum occulatum) were additional findings. There have been no further descriptions in the literature since 1974. |

The patients also present with generalized osteoporosis and a history of frequent fractures. This syndrome is similar to Prader-Willi syndrome, but the hand contractures and osteoporosis, together with the lack of hypotonia, indicate this is a different entity. |

| Female restricted epilepsy with intellectual disability is a rare X-linked epilepsy syndrome characterized by febrile or afebrile seizures (mainly tonic-clonic, but also absence, myoclonic, and atonic) starting in the first years of life and, in most cases, developmental delay and intellectual disability of variable severity. Behavioral disturbances (e.g. autistic features, hyperactivity, and aggressiveness) are also frequently associated. This disease affects exclusively females, with male carriers being unaffected, despite an X-linked inheritance. |
