Identification of a locus on chromosome 14q for idiopathic basal ganglia calcification (Fahr disease)

Article Abstract:

Idiopathic basal ganglia calcification (IBGC), or Fahr disease, is discussed relative to identification of a locus on chromosome 14q for this neurodegenerative syndrome associated with various movement/cognitive disorders. A multigenerational family with dominantly inherited IBGC was identified and a whole-genome scan performed using polymorphic microsatellite markers to identify the first chromosomal locus for the disorder. Age at onset seemed to be decreasing by an average of more than 20 years with each transmission, in accordance with genetic anticipation.

Multiple ATM-dependent pathways: an explanation for pleiotropy

Article Abstract:

Ataxia-telangiectasia (AT) is a rare autosomal recessive genetic disorder, a syndrome known for its pleiotropic phenotype with degenerative neurological function, especially in the cerebellum, and oculocutaneous telangiectasias. Other problems may also be involved ad the cell lines from AT patients have characteristic abnormalities. ATM is the gene mutated in AT. Multiple ATM-dependent pathways may furnish an explanation for pleiotropy. Perhaps therapies can be developed for the disorder with increased understanding of genetic aspects.
