DYM

This gene encodes a protein which is necessary for normal skeletal development and brain function. Mutations in this gene are associated with two types of recessive osteochondrodysplasia, Dyggve-Melchior-Clausen (DMC) dysplasia and Smith-McCort (SMC) dysplasia, which involve both skeletal defects and mental retardation.

Full Name

dymeclin

Research Area

Necessary for correct organization of Golgi apparatus. Involved in bone development.

Biological Process

Bone development Source: UniProtKB
Golgi organization Source: UniProtKB

Cellular Location

Golgi apparatus; Cytoplasm; Membrane. Sequence analysis programs clearly predict 1 transmembrane region. However, PubMed:18996921 shows that it is not a stably anchored transmembrane protein but it weakly associates with the Golgi apparatus and shuttles between the Golgi and the cytosol.

Involvement in disease

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.
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.

PTM

Myristoylated in vitro; myristoylation is not essential for protein targeting to Golgi compartment.
