Genomic Portrait of a Sporadic Amyotrophic Lateral Sclerosis Case in a Large Spinocerebellar Ataxia Type 1 Family.

ABSTRACT:

Background

Repeat expansions in the spinocerebellar ataxia type 1 (SCA1) gene ATXN1 increases the risk for amyotrophic lateral sclerosis (ALS), supporting a relationship between these disorders. We recently reported the co-existence, in a large SCA1 family, of a clinically definite ALS individual bearing an intermediate ATXN1 expansion and SCA1 patients with a full expansion, some of which manifested signs of lower motor neuron involvement.

Methods

In this study, we employed a systems biology approach that integrated multiple genomic analyses of the ALS patient and some SCA1 family members.

Results

Our analysis identified common and distinctive candidate genes/variants and related biological processes that, in addition to or in combination with ATXN1<
