Genes affected

KLHL1 (HGNC:6352): (kelch like family member 1) The KLHL1 protein belongs to a family of actin-organizing proteins related to Drosophila Kelch (Nemes et al., 2000 [PubMed 10888605]).[supplied by OMIM, Feb 2010]

KLHL1 links:

ATXN8OS (HGNC:10561): (ATXN8 opposite strand lncRNA) This gene is an antisense transcript to the KLHL1 gene (homolog to the Drosophila KELCH gene); it does not itself appear to be protein coding. A TAC/TGC trinucleotide repeat expansion that is incorporated into this gene transcript, but not the KLHL1 transcript, causes spinocerebellar ataxia type 8. Presumably the expansion interferes with normal antisense function of this transcript. [provided by RefSeq, Oct 2008]
