Split hand/foot malformation is a heterogeneous congenital disorder mainly presented with a median cleft of hands or/and feet. It can be associated with long bone aplasia, a syndrome also known as split hand/foot syndrome with long bone deficiency (SHFLD), which is a very rare condition. We report a very rare case of a male fetus with SHFLD syndrome combined with fibular aplasia, tibial campomelia, and oligosyndactyly (FATCO) syndrome. FATCO syndrome is also an extremely infrequent congenital limb defect by itself. Based on our review of the literature, there appears to be no other FATCO case reported in Greece.

Fibular aplasia, tibial campomelia, and oligosyndactyly (FATCO) syndrome (MIM 246570) is a rare disorder characterized by specific skeletal findings (fibular aplasia, shortened or bowed tibia, and oligosyndactyly of the foot and/or hand). Typically, no other anomalies, craniofacial dysmorphism, or developmental delays are associated. Here we report three unrelated individuals with limb anomalies consistent with FATCO syndrome who have been followed clinically for 5 years. Genetic testing of previously reported individuals with FATCO syndrome has not revealed a genetic diagnosis. However, no broader sequencing approaches have been reported. We describe the results of the three individuals with FATCO syndrome from exome and genome sequencing, all of which was nondiagnostic. Our study suggests that FATCO syndrome is not the result of a simple monogenic etiology.

Fibular aplasia, tibial campomelia, and oligosyndactyly (FATCO syndrome) is a rare, genetic, congenital limb malformation characterised by unilateral or bilateral fibular aplasia, tibial campomelia, and lower limb oligosyndactyly involving the lateral rays. A newborn male born at term via a Caesarean Section presented with malformations consisting of tibial campomelia, unilateral fibular hypoplasia, and oligosyndactyly, a "FATCO variant" case. On radiographic examination, an anterolateral shortened and bowed right lower limb at the distal third of the tibia, a rudimentary right fibula and absence of three rays on right foot were revealed. "FATCO syndrome" although rare may be linked to involvement of different body systems with morbidity and mortality. Proper parent counseling is a key aspect of this syndrome. Timely diagnosis and management with a multidisciplinary approach is essential to avoid lifelong disability, which can be a hurdle in a developing country.

The syndrome of fibular aplasia, tibial campomelia, and oligosyndactyly (FATCO syndrome) is a rare genetic disease that has been increasingly reported over the past 40 years. We report the case of a newborn boy with unilateral skeletal abnormalities that were evident clinically and radiologically. The baby was an infant of a diabetic mother, and the Egyptian parents were consanguineous with a strong family history of genetic diseases and congenital anomalies. Besides describing a new case report of this syndrome, we emphasize the importance of prenatal diagnosis and genetic counseling, especially for families at high risk for genetic diseases in developing countries.

Fibular aplasia, tibial campomelia, and oligosyndactyly (FATCO) syndrome is a rare disorder with unknown molecular basis. Since it is a rare disorder, so it is commendable to report the each case, due to its sporadic incidence and paucity of the standardized management protocol for their management. It is a case report of newly born male baby, whose anxious parents presented to the outpatient department with a deformity in the left lower limb. This resembled the FATCO syndrome. After clinico-radiological workup, it was categorized as a variant of FATCO syndrome. Counseling of parents should be done and let them realize that what is inescapable with this syndrome and what is bound to happen during the treatment.
