Marbach-Rustad progeroid syndrome (MARUPS) is characterized by progeroid appearance with little subcutaneous fat and triangular facies, growth retardation with short stature, hypoplastic mandible crowded with unerupted supernumerary teeth, and cerebellar intention tremor. Psychomotor development is normal. Although features are reminiscent of Hutchinson-Gilford progeria syndrome (HGPS; 176670), MARUPS is less severe, with a relatively good prognosis. Two patients have been reported (Marbach et al., 2019). [from OMIM]

Juvenile-onset cataract-46 with or without arrhythmic cardiomyopathy (CTRCT46) is characterized by onset of cataract in the first decades of life, associated with variable onset of a severe form of arrhythmic cardiomyopathy, with mild impairment of left ventricular systolic function but severe ventricular arrhythmias resulting in sudden cardiac death. Affected individuals are descendants of the Hutterite founder population (Abdelfatah et al., 2019). [from OMIM]
