Work over the past 25 years has resulted in the identification of genes responsible for ~50%
of the estimated 7,000 rare monogenic diseases, and it is predicted that most of the …

Deep phenotyping has been defined as the precise and comprehensive analysis of phenotypic
abnormalities in which the individual components of the phenotype are observed and …

The International Rare Diseases Research Consortium (IRDiRC) was founded in 2011 with
the conviction that rare diseases research had reached a critical juncture. Proof of principle …

Amyotrophic lateral sclerosis (ALS) is a paralytic and usually fatal disorder caused by motor-neuron
degeneration in the brain and spinal cord. Most cases of ALS are sporadic but about …

Megalencephaly-capillary malformation (MCAP) and megalencephaly-polymicrogyria-polydactyly-hydrocephalus

Background The late-onset cerebellar ataxias (LOCAs) have largely resisted molecular
diagnosis. Methods We sequenced the genomes of six persons with autosomal dominant LOCA …

There are few better examples of the need for data sharing than in the rare disease community,
where patients, physicians, and researchers must search for “the needle in a haystack” to …

Provision of a molecularly confirmed diagnosis in a timely manner for children and adults with
rare genetic diseases shortens their "diagnostic odyssey," improves disease management, …

It is estimated that 350 million individuals worldwide suffer from rare diseases, which are
predominantly caused by mutation in a single gene 1 . The current molecular diagnostic rate is …
