Abstract:Given the clinical complexities of Cornelia de Lange Syndrome (CdLS), the Center for CdLS and Related Diagnoses at The Children's Hospital of Philadelphia (CHOP) and The Multidisciplinary Clinic for Adolescents and Adults at Greater Baltimore Medical Center (GBMC) were established to develop a comprehensive approach to clinical management and research issues relevant to CdLS. Little work has been done to evaluate the general utility of a multispecialty approach to patient care. Previous research demonstrates s… Show more
“…Access to clinical evaluation, counselling and follow-up by a multidisciplinary team is likely to improve health care and increase quality of life. Recognized barriers to accessing care include health or behavioural complications, geographical isolation and financial considerations [185][186][187] . Individuals with CdLS are now likely to live into adulthood and old age and thus risk developing common chronic diseases in addition to CdLS-related morbidities.…”
Cornelia de Lange syndrome (CdLS) is an archetypical genetic syndrome that is characterized by intellectual disability, well-defined facial features, upper limb anomalies and atypical growth, among numerous other signs and symptoms. It is caused by variants in any one of seven genes, all of which have a structural or regulatory function in the cohesin complex. Although recent advances in next-generation sequencing have improved molecular diagnostics, marked heterogeneity exists in clinical and molecular diagnostic approaches and care practices worldwide. Here, we outline a series of recommendations that document the consensus of a group of international experts on clinical diagnostic criteria, both for classic CdLS and non-classic CdLS phenotypes, molecular investigations, long-term management and care planning.

“…Molecular genetic testing assists in making a confirmative diagnosis of CdLS. Once the diagnosis is acquired, lifelong medical care and multidisciplinary and social care are urgently needed to improve the patient’s health and increase their quality of life ( 3 , 27 , 28 ). Interdisciplinary management integrates doctors from different disciplines to establish a treatment team, which enables patients with CdLS to be evaluated from different professional perspectives and it proposes syndrome-specific, individualized treatment plans.…”
PurposeCornelia de Lange syndrome (CdLS) is a rare congenital developmental disorder, and cases caused by variants in SMC3 are infrequent. This article describes a case of CdLS related to a pathogenic variant in SMC3 and performs a literature review.MethodsWe collected clinical data and biological samples from a 12-year-old boy with “short stature for 11 years”. Gene variants in the proband were detected by whole-exome sequencing, and the variants in his parents were verified by Sanger sequencing. All SMC3-related CdLS patients from the PubMed and Web of Science databases were collected and summarized using the available data.ResultsA pathogenic variant in SMC3 in the proband, c.1942A>G, was identified. Neither of his parents carried the same variant. Twenty-eight patients were diagnosed with CdLS with variants in SMC3, including the cases in this study and those reported in the literature, where half of the variant types were missense, followed by 32% (9/28) with a deletion and 11% (3/28) with a duplication. All patients showed symptoms of verbal development delay and intellectual disability to different degrees, and 90% patients had long eyelashes while 89% patients had arched eyebrows.ConclusionThis study summarized different gene variants in SMC3 and the frequencies of the various clinical manifestations according to the reported literature. For CdLS caused by SMC3 variants, short stature and facial dysmorphic features are the two most important clinical clues. Definite diagnosis of this rare disease may be challenging clinically; thus, it is significant to use molecular diagnosis.
“…In the neurological rehabilitation area, to identify these aspects is not easy. Children with CdLS were recommended to have a multidisciplinary intervention [9,10]. Two studies regarding CdLS [1,6] describe clinical and genetic aspects, with no report of physical therapy for these cases.…”
Introduction: The Cornelia de Lange Syndrome (CdLS) is a rare genetic syndrome. Children with CdLS usually require physical therapy, however the efficacy of physical therapy intervention in this population is lacking in the research literature. Objective: The aim of this study was to report the effect of Intensive Neuromotor Therapy (INMT) on gross motor function and participation of a child with CdLS using the International Classification of Functioning, Disabilities and Health (ICF) model. Method: A Brazilian child with CdLS was followed for over seven months while undergoing three modules of INMT. Results: The child demonstrated an evolution of gross motor function with gains of 11.28% in the first module, 9.22% in the second module, and 10.29% in the third module of INMT. Conclusion: INMT resulted in improvements in gross motor function and participation during daily activities in a child with CDLS. Further studies of larger cohorts are needed to investigate the efficacy of INMT in children with CdLS.
