OMIM : ⁵⁷ Singleton-Merten syndrome (SGMRT) is an uncommon autosomal dominant disorder characterized by abnormalities of blood vessels, teeth, and bone. Calcifications of the aorta and aortic and mitral valves occur in childhood or puberty and can lead to early death. Dental findings include delayed primary tooth exfoliation and permanent tooth eruption, truncated tooth root formation, early-onset periodontal disease, and severe root and alveolar bone resorption associated with dysregulated mineralization, leading to tooth loss. Osseous features consist of osteoporosis, either generalized or limited to distal extremities, distal limb osteolysis, widened medullary cavities, and easy tearing of tendons from bone. Less common features are mild facial dysmorphism (high anterior hair line, broad forehead, smooth philtrum, thin upper vermilion border), generalized muscle weakness, psoriasis, early-onset glaucoma, and recurrent infections. The disorder manifests with variable inter- and intrafamilial phenotypes (summary by Rutsch et al., 2015). (182250)

MalaCards based summary : Singleton-Merten Syndrome 1, also known as sgmrt1, is related to singleton-merten syndrome 2 and aicardi-goutieres syndrome 7. An important gene associated with Singleton-Merten Syndrome 1 is IFIH1 (Interferon Induced With Helicase C Domain 1). Affiliated tissues include bone, skin and heart, and related phenotypes are genu valgum and muscular hypotonia

UniProtKB/Swiss-Prot : ⁷⁵ Singleton-Merten syndrome 1: An autosomal dominant disorder with variable expression. Core features are marked aortic calcification, dental anomalies, osteopenia, acro- osteolysis, and to a lesser extent glaucoma, psoriasis, muscle weakness, and joint laxity. Dental anomalies include delayed eruption and immature root formation of anterior permanent teeth, early loss of permanent teeth due to short roots, acute root resorption, high caries, and aggressive alveolar bone loss. Additional clinical manifestations include particular facial characteristics and abnormal joint and muscle ligaments.
