Craniotubular Dysplasia Ikegawa type is a sclerosing bone disorder recently identified in five patients from four independent Indian families. It is caused by homozygous or compound heterozygous mutations in TMEM53. Deficient TMEM53 leads to overactive BMP signaling which promotes bone formation. Here, we present another three siblings with introni...
