There are at least 15 genes on the X-chromosome that have been constantly or occasionally associated with a pathological cerebellar phenotype.

Boehnke, M. Freije, D. The results showed that among gay brothers, the concordance rate for markers from the Xq28 region were significantly greater than expected for random Mendelian segregation, indicating that a link did exist in that small sample.
