The V65M variant in the KCNJ8 gene was associated with Cantú syndrome, a rare genetic condition characterized by congenital hypertrichosis and cardiovascular abnormalities including an enlarged, hypercontractile heart (Brownstein et al., 2013; Cooper et al., 2014). This evidence concerns the gene KCNJ8 and hypertrichotic osteochondrodysplasia Cantu type.
