Acro-renal-ocular syndrome

Acro-renal-ocular syndrome is an extremely rare congenital malformation syndrome characterized by a combination of limb (acral), kidney (renal), and eye (ocular) abnormalities. The condition is present at birth and affects multiple organ systems. Limb anomalies typically include split hand and split foot malformations (ectrodactyly), radial ray defects, and other digital abnormalities such as absent or hypoplastic thumbs. Renal malformations may include renal agenesis (absence of one or both kidneys), ectopic kidneys, horseshoe kidney, or other structural kidney anomalies that can range from mild to severe. Ocular features can include Duane anomaly (a type of eye movement disorder), coloboma, and other eye malformations. The syndrome shares clinical overlap with acro-renal syndrome and other conditions involving limb-renal associations, but is distinguished by the additional presence of ocular anomalies. Some cases have also been reported with mild facial dysmorphism. The severity of the condition varies considerably between affected individuals, even within the same family, making clinical diagnosis challenging. There is no specific cure or targeted therapy for acro-renal-ocular syndrome. Management is supportive and multidisciplinary, focusing on the specific malformations present in each individual. This may include surgical correction of limb anomalies, monitoring and management of renal function, ophthalmologic care, and orthopedic interventions. Long-term prognosis depends largely on the severity of renal involvement. Genetic counseling is recommended for affected families.
