TBP and cleidocranial dysplasia 1: Basu et al., 2020 [62] demonstrated this aberrant phase separation for proteins encoded by HOXD13, HOXA13, RUNX2, and TBP, which are genes with repeat expansions encoding polyA or polyQ, associated with synpolydactyly, hand-foot genital syndrome (HFGS), cleidocranial dysplasia (CCD), and spinocerebellar ataxia type 17 (SCA17), respectively.
