Shprintzen-Goldberg syndrome (SGS) is a rare disorder characterized by a Marfan-like habitus, mental retardation and craniosynostosis. Cardiac abnormalities, such as aortic root dilation have also been noted as well as several skeletal abnormalities. Its nosological status is unclear as it is hard to delineate SGS from similar disorders, such as Furlong, Marfan type II, Camurati-Engelmann and Loeys-Dietz syndromes. It has been suggested that these conditions represent a phenotypical spectrum associated with aberrant TGF-beta signalling. In support of this notion, we found a novel TGFBR2 missense mutation in a patient with features of SGS.

Shprintzen-Goldberg syndrome is a rare systemic connective tissue disorder caused by heterozygous mutations in the Sloan-Kettering Institute (SKI) gene. The clinical presentation is reminiscent of Marfan and Loeys-Dietz syndromes, making differential diagnosis challenging. Shprintzen-Goldberg syndrome's distinctive features are craniosynostosis and learning disabilities.

Shprintzen-Goldberg-syndrome (SGS) is caused by pathogenic exon 1 variants of SKI. Symptoms include dysmorphic features, skeletal and cardiovascular comorbidities, and cognitive and developmental impairments. We delineated the neurodevelopmental and behavioral features of SGS, as they are not well-documented.

Loeys-Dietz syndrome (LDS) is a very rare connective tissue disorder with autosomal dominant inheritance, characterized by the involvement of the cardiovascular, musculoskeletal, and cutaneous systems, along with dysmorphic facial features. Currently, there are limited data regarding this disease. This case presents a clinical observation of a 17-year-old boy with acute onset of sensorimotor paraparesis and genetically confirmed LDS.

Shprintzen-Goldberg syndrome (SGS) is an autosomal dominant syndrome caused by de novo gene mutations. It is characterized by a number of congenital defects such as craniofacial, skeletal, neurological, and connective tissue abnormalities. It is characterized by craniosynostosis and marfanoid features.

Heterozygous deleterious variants in SKI cause Shprintzen-Goldberg Syndrome, which is mainly characterized by craniofacial features, neurodevelopmental disorder and thoracic aorta dilatations/aneurysms. The encoded protein is a member of the transforming growth factor beta signaling. Paucity of reported studies exploring the SGS molecular pathogenesis hampers disease recognition and clinical interpretation of private variants.
