Genes affected

CCDC170 (HGNC:21177): (coiled-coil domain containing 170) The function of this gene and its encoded protein is not known. Several genome-wide association studies have implicated the region around this gene to be involved in breast cancer and bone mineral density, but no link to this specific gene has been found.
