Recessively Inherited Parkinsonism

Recessively inherited myotonia congenita.

Recessively inherited coagulation disorders.

Deficiencies of coagulation factors other than factor VIII and factor IX that cause bleeding disorders are inherited as autosomal recessive traits and are rare, with prevalences in the general population varying between 1 in 500 000 and 1 in 2 million for the homozygous forms. As a consequence of the rarity of these deficiencies, the type and severity of bleeding symptoms, the underlying molecu...

Recessively inherited brachydactyly type C.

The Bell classification of brachydactyly' divides this group of conditions into types Al to A5, B, C, D, and E. Fitch2 in 1979 suggested that types A4 to A5 be omitted because the latter is indistinguishable radiologically from type B, while type A4 is possibly a mild expression of Al. She suggested that type E should be further subdivided depending on which metacarpals are involved. The table ...

Recessively inherited parkinsonism: effect of ATP13A2 mutations on the clinical and neuroimaging phenotype.

OBJECTIVE To determine clinical features and to identify changes in brain structure and function in compound heterozygous and heterozygous ATP13A2 mutation carriers. DESIGN Prospective multimodal clinical and neuroimaging study. SETTING University of Lübeck, Lübeck, Germany. PARTICIPANTS Eight family members of a large Chilean pedigree with Kufor-Rakeb syndrome (KRS). INTERVENTIONS Clin...

Recessively inherited L-DOPA-responsive parkinsonism in infancy caused by a point mutation (L205P) in the tyrosine hydroxylase gene.

Tyrosine hydroxylase (TH) catalyzes the conversion of L-tyrosine to L-dihydroxyphenylalanine (L-DOPA), the rate-limiting step in the biosynthesis of dopamine. This report describes a missense point mutation in the human TH (hTH) gene in a girl presenting parkinsonian symptoms in early infancy and a very low level of the dopamine metabolite homovanillic acid in the CSF. DNA sequencing revealed a...
