what is the chromosome for als
One autosomal recessive form of the disorder (known as ALS2) has been linked to the long arm of chromosome 2 (2q33). ALS2 is a slowly progressive, early-onset form of the disease, sometimes called juvenile inherited ALS and found in populations in North Africa and the Middle East.
The study therefore describes a major cause of familial ALS in the Finland located on chromosome 9p21. Furthermore, the overlap with the risk haplotype (a combination of DNA sequences) recently also reported for frontotemporal dementia provides further evidence of a shared genetic cause for these two neurodegenerative diseases.
