Gnathodiaphyseal dysplasia (GDD; OMIM#166260) is a rare skeletal disorder which is mainly characterized by cemento-osseous lesions in mandibles, bone fragility, bowing and diaphyseal sclerosis of tubular bones. GDD is caused by point mutations in Anoctamin-5 (ANO5); however, the disease mechanisms remain unclear. Here we generated Ano5-knockout (KO) mice using a CRISPR/Cas 9 approach to study loss of function aspects of GDD mutations. Homozygous Ano5 knockout mice (Ano5-/-) replicate some typical traits of human GDD including massive jawbones, bowing tibia, sclerosis and cortical thickening of femoral and tibial diaphyses. Serum alkaline phosphatase (ALP) levels were elevated in Ano5-/-mice as in GDD patients. Calvaria-derived Ano5-/-osteoblast cultures show increased osteoblastogenesis, which is consistent with our previous in vitro observations. Bone matrix is hypermineralized, and the expression of bone formation-related factors is enhanced in Ano5-/-mice, suggesting that the osteogenic anomaly arises from a genetic disruption of Ano5. We believe this new mouse model will shed more light on the development of skeletal abnormalities in GDD on a cellular and molecular level.
