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.

Bruck syndrome is a rare, autosomal-recessive condition associated with features of both arthrogryposis and osteogenesis imperfecta. It is characterised by congenital large joint contractures with pterygia and bone fragility, leading to fractures and deformities, along with a short stature caused by progressive skeletal deformities. There are fewer than 50 described cases of Bruck syndrome in the literature, with no reported cases in pregnancy.

Although next-generation sequencing has enabled diagnoses for many patients with Mendelian disorders, the majority remain undiagnosed. Here, we present a sibling pair who were clinically diagnosed with Escobar syndrome, however targeted gene testing was negative. Exome sequencing (ES), and later genome sequencing (GS), revealed compound heterozygous TTN variants in both siblings, a maternally inherited frameshift variant [(NM_133378.

Arthrogryposis is a clinical feature defined by congenital joint contractures in two or more different body areas which occurs in between 1/3000 and 1/5000 live births. Variants in multiple genes have been associated with distal arthrogryposis syndromes. Heterozygous variants in MYH3 have been identified to cause the dominantly-inherited distal arthrogryposis conditions, Freeman-Sheldon syndrome, Sheldon-Hall syndrome, and multiple pterygium syndrome.

Congenital myopathies are a genetically heterogeneous group of neuromuscular disorders that commonly present with congenital hypotonia and weakness but can also present broadly. The most severe presentation is neonatal with arthrogryposis and, rarely, fetal akinesia and pterygia, features also seen in lethal multiple pterygium syndrome (LMPS). We describe two fetuses with similar phenotype, including hydrops fetalis, large cystic hygromas, bilateral talipes, and fetal akinesia in the second trimester.
