Genes affected

FAM186B (HGNC:25296): (family with sequence similarity 186 member B) This gene product is a member of the FAM186 family, however, its exact function is not known. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2009]

FAM186B links:

PRPF40B (HGNC:25031): (pre-mRNA processing factor 40 homolog B) This gene encodes a WW-domain containing protein similar to yeast splicing factor PRP40. This protein has been shown to interact with Huntingtin and methyl CpG binding protein 2 (MeCP2). Alternative splicing results in different transcript variants. [provided by RefSeq, Aug 2014]
