Further recently described variant forms of EDS, such as that with progressive scoliosis and deafness (OMIM: 614557) due to biallelic mutations in FKBP14, may also show clinical overlap with BCS [18], though the full range of clinical phenotypes due to mutations in these and other newly identified genes requires further definition. This evidence concerns the gene FKBP14 and Ehlers-Danlos syndrome.
