Abstract
Schinzel-Giedion syndrome is a rare autosomal dominant disorder comprising postnatal growth failure, profound developmental delay, seizures, facial dysmorphisms, genitourinary, skeletal, neurological, and cardiac defects. It was recently revealed that Schinzel-Giedion syndrome is caused by de novo mutations in SETBP1, but there are few reports of this syndrome with molecular confirmation. We describe two unrelated Brazilian patients with Schinzel-Giedion syndrome, one of them carrying a novel mutation. We also present a review of clinical manifestations of the syndrome, comparing our cases to patients reported in literature emphasizing the importance of the facial gestalt associated with neurological involvement for diagnostic suspicion of this syndrome.

An Pediatr (Barc) 2014; 82:e12-6. [PMID: 25082129 DOI: 10.1016/j.anpedi.2014.06.017] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/19/2014] [Revised: 06/16/2014] [Accepted: 06/23/2014] [Indexed: 11/26/2022] Open
Abstract
Schinzel-Giedion syndrome (SGS) (#MIM 269150) is a rare genetic disorder characterized by very marked craniofacial dysmorphism, multiple congenital anomalies and severe intellectual disability. Most affected patients die in early childhood. SETBP1 was identified as the causative gene, but a limited number of patients with molecular confirmation have been reported to date. The case is reported of a 4 and a half year-old male patient, affected by SGS. SETBP1 sequencing analysis revealed the presence of a non-previously described mutation: c.2608G>T (p.Gly870Cys). The clinical features and differential diagnosis of this rare condition are reviewed. Dysmorphic features are strongly suggestive of SGS. Its clinical recognition is essential to enable an early diagnosis, a proper follow-up, and to provide the family with genetic counseling. To date, this is the seventeenth SGS patient published with SETBP1 mutation, and the first in Spain, helping to widen clinical and molecular knowledge of the disease.

Clinical and radiological findings in Schinzel-Giedion syndrome. Eur J Pediatr 2008; 167:1399-407. [PMID: 18461363 DOI: 10.1007/s00431-008-0683-4] [Citation(s) in RCA: 13] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2007] [Revised: 01/25/2008] [Accepted: 01/30/2008] [Indexed: 10/22/2022]
Abstract
The absence of a definitive genetic test for the autosomal recessive condition Schinzel-Giedion syndrome is a significant handicap to the recognition of this disorder. Radiological features have been an important aspect of many of the published cases. In a series of six cases, we now establish a consistency among many of the radiological features in affected cases which will be an important diagnostic aid in identifying future cases. This is confirmed by reference to an extensive review of previously published instances of the syndrome. Moreover, the clinical data, including previously unpublished photographs, which we detail from our patients will assist in enhanced diagnosis in the future.
