Selective tooth agenesis-9 (STHAG9) is an autosomal dominant disorder characterized by agenesis of various teeth. Other features include taurodontism, microdontia, short tooth roots, sparse and slow-growing hair, and dry and itchy skin (Kantaputra et al., 2015).
For a general phenotypic description and a discussion of genetic heterogeneity of selective tooth agenesis, see STHAG1 (106600). [from
