Genes affected
FAM9B (HGNC:18404): (family with sequence similarity 9 member B) This gene is a member of a gene family which arose through duplication on the X chromosome. The encoded protein may be localized to the nucleus as the protein contains several nuclear localization signals, and has similarity to a synaptonemal complex protein. [provided by RefSeq, Aug 2011]
