From NCBI Gene:
This gene encodes a protein which regulates Golgi-associated secretory pathways that are essential to endochondral bone formation during early development. This gene is also believed to play a role in early brain development. This gene is widely expressed in embryos and is particularly abundant in chodrocytes and brain tissues. It encodes a peripheral membrane protein which shuttles between the cytosol and Golgi complex. Mutations in this gene are associated with two types of recessive osteochondrodysplasia: Dyggve-Melchior-Clausen (DMC) dysplasia and Smith-McCort (SMC) dysplasia. [provided by RefSeq, Jun 2017]
Necessary for correct organization of Golgi apparatus. Involved in bone development.

- Smith-McCort dysplasia 1
- Dyggve-Melchior-Clausen syndrome
Smith-McCort dysplasia 1 (SMC1): A rare autosomal recessive osteochondrodysplasia with skeletal features identical to those of Dyggve-Melchior-Clausen syndrome, but with normal intelligence and no microcephaly. It is characterized by short limbs and trunk with barrel-shaped chest. The radiographic phenotype includes platyspondyly, generalized abnormalities of the epiphyses and metaphyses, and a distinctive lacy appearance of the iliac crest. [MIM:607326]
Dyggve-Melchior-Clausen syndrome (DMC): A rare autosomal recessive disorder belonging to the group of spondyloepimetaphyseal dysplasias. DMC is characterized by progressive short stature with short trunk dwarfism, microcephaly, protruding sternum, and psychomotor retardation. Radiological features include a platyspondyly with double vertebral humps, an epiphyso-metaphyseal dysplasia and lacy pelvis iliac crests. [MIM:223800]
