Summaries for Singleton-Merten Syndrome 2

UniProtKB/Swiss-Prot : 74 Singleton-Merten syndrome 2: A form of Singleton-Merten syndrome, an autosomal dominant disorder characterized by marked aortic calcification, dental anomalies, osteopenia, acro-osteolysis, and to a lesser extent glaucoma, psoriasis, muscle weakness, and joint laxity. Additional clinical manifestations include particular facial characteristics and abnormal joint and muscle ligaments. SGMRT2 is an atypical form characterized by variable expression of glaucoma, aortic calcification, and skeletal abnormalities, without dental anomalies.

MalaCards based summary : Singleton-Merten Syndrome 2, is also known as sgmrt2. An important gene associated with Singleton-Merten Syndrome 2 is DDX58 (DExD/H-Box Helicase 58). Affiliated tissues include smooth muscle, and related phenotypes are short stature and aortic valve stenosis

OMIM : 57 Singleton-Merten syndrome-2 is characterized by variable expression of glaucoma, aortic calcification, and skeletal abnormalities, without dental anomalies (summary by Jang et al., 2015). For a general phenotypic description and discussion of genetic heterogeneity of Singleton-Merten syndrome, see SGMRT1 (182250). (616298)
