CHARGE syndrome is a rare autosomal dominant syndrome characterized by multiple congenital anomalies including coloboma, heart defects, ear anomalies, and developmental delay, caused by pathogenic variants in the CHD7 gene. The discovery of the molecular basis of this syndrome increased the number of cases reported and expanded the phenotype and clinical variability. Limb anomalies are occasional clinical findings in this syndrome, present in about 30% of reported cases. The occurrence of limb anomalies in this syndrome suggests that it should be considered as part of the phenotypic spectrum. Here, we describe an individual with CHARGE syndrome presenting unilateral monodactyly.

Escobar syndrome (nonlethal type of multiple pterygium syndrome) is a very rare genetic disorder. The central manifestations of Escobar syndrome are the presence of multiple pterygia, fixed joint contractures, and characteristic facies. Here, we report a case of Escobar syndrome with additional features such as monodactyly and hypoplastic pectoralis muscle.
