Overview

Ventricular extrasystoles with syncopal episodes-perodactyly-Robin sequence syndrome is an extremely rare genetic condition that affects multiple body systems. It is sometimes referred to by its Orphanet identifier ORPHA:3201. This syndrome combines three main features: heart rhythm problems (ventricular extrasystoles, which are extra heartbeats originating from the lower chambers of the heart, sometimes causing fainting spells or syncopal episodes), limb abnormalities called perodactyly (missing or underdeveloped fingers or toes), and Pierre Robin sequence (a combination of a small lower jaw, a tongue that falls back into the throat, and often a cleft palate). Because the heart rhythm disturbances can cause fainting and potentially dangerous episodes, cardiac monitoring is an important part of managing this condition. The Robin sequence component can cause breathing and feeding difficulties, especially in newborns and infants. Treatment is supportive and addresses each symptom individually. Heart rhythm problems may require medication or monitoring, while the jaw and palate abnormalities may need surgical correction. Limb differences may benefit from occupational therapy or adaptive devices. Because this syndrome is so rare, management is typically coordinated by a team of specialists familiar with each aspect of the condition. Very few cases have been described in the medical literature, so knowledge about the full range of symptoms and long-term outcomes remains limited.
