The Schinzel-Giedion syndrome is an infrequently described malformation syndrome, mainly characterized by a profound mental deficiency, a typical face including a midface hypoplasia, urogenital abnormalities, and minor radiographic features. Death prior to two year of age is the rule. A boy with typical features of the syndrome is described. He died at the age of 21 months. This is the first case of this syndrome reported from Croatia. The recurrence in only one of the 20 families, does not firmly sustain an autosomal recessive pattern of inheritance, although this still remains possible.

The management of children with syndromes associated with an increased risk of benign and malignant neoplasms is a complex challenge for healthcare professionals. The 2023 AACR Childhood Cancer Predisposition Workshop provided updated consensus guidelines on cancer surveillance in these syndromes, aiming to improve early detection, intervention, and reduce morbidity associated with such neoplasms. In this paper, we review several of the rare conditions discussed in this workshop.

Schinzel-Giedion syndrome (SGS) is a severe multisystem disorder characterized by distinctive facial features, profound intellectual disability, refractory epilepsy, cortical visual impairment, hearing loss, and various congenital anomalies. SGS is attributed to gain-of-function (GoF) variants in the SETBP1 gene, with reported variants causing canonical SGS located within a 12 bp hotspot region encoding SETBP1 residues aa868-871 (degron). Here, we describe a case of typical SGS caused by a novel heterozygous missense variant, D874V, adjacent to the degron.

Introduction: gene variants that decrease or eliminate protein activity have been associated with phenotypes characterized by speech apraxia and intellectual disabilities. This condition, distinctly separated from Schinzel-Giedion syndrome, is referred to as autosomal dominant mental retardation 29 (ADR29).
Case Presentation: In this report, we present the case of a 6-year-old male patient exhibiting fine and global motor skill impairments along with expressive language delay.
