In this study, we aim at defining the CULA etiology of patients that have been evaluated at the Modena University Hospital's Congenital Hand Malformations multidisciplinary clinic in the years 2004 to 2012.<\/jats:p><\/jats:sec><jats:sec><jats:title>METHODS<\/jats:title><jats:p>Medical records of 487 patients were retrospectively reviewed. On the basis of clinical, anamnestic, and genetic data, the CULA were distributed into two main groups: (1) non\u2010Mendelian etiology, including prenatal exposure, somatic mutations and amniotic bands; and (2) Mendelian etiology, including single gene and genomic\/chromosomal diseases. CULA were further grouped according to the embryological damage (formation, separation and growth defects) and to the involved axis (radial, ulnar, central).<\/jats:p><\/jats:sec><jats:sec><jats:title>RESULTS<\/jats:title><jats:p>A Mendelian etiology was diagnosed in 199 patients (40.9%), whereas the remaining 288 cases (59.1%) were described as non\u2010Mendelian. The involvement of the lower limbs, the presence of malformations in other organs and facial dysmorphisms were significantly more represented in the Mendelian cases. The formation defects were significantly more frequent in the non\u2010Mendelian group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001), whereas the frequency of separation defects was higher in the Mendelian cases (<jats:italic>p<\/jats:italic>\u2009=\u20090.0025). Patients with non\u2010Mendelian etiologies showed a significantly higher frequency of central defects (<jats:italic>p<\/jats:italic>\u2009=\u20090.0031).<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>The two etiologies differ in terms of patient's clinical features, morphology defect and axis involvement. This data may be helpful to the clinician during the patient's diagnostic workup by indicating the necessity for genetic testing and for determining the anomaly's recurrence risk. <jats:italic>Birth Defects Research (Part A) 97:798\u2013805, 2013<\/jats:italic>. \u00a9 2013 Wiley Periodicals, Inc.<\/jats:p><\/jats:sec>","DOI":"10.1002\/bdra.23212","type":"journal-article","created":{"date-parts":[[2013,12,17]],"date-time":"2013-12-17T08:43:09Z","timestamp":1387269789000},"page":"798-805","source":"Crossref","is-referenced-by-count":18,"title":["Genetic Basis of Congenital Upper Limb Anomalies: Analysis of 487 Cases of a Specialized Clinic"],"prefix":"10.1002","volume":"97","author":[{"given":"Diana","family":"Carli","sequence":"first","affiliation":[{"name":"Medical Genetics, Department of Medical and Surgical Sciences University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tracy","family":"Fairplay","sequence":"additional","affiliation":[{"name":"Hand Rehabilitation, Department of Locomotor System Diseases University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paola","family":"Ferrari","sequence":"additional","affiliation":[{"name":"Pediatrics, Department of Medical and Surgical Sciences University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Silvana","family":"Sartini","sequence":"additional","affiliation":[{"name":"Hand Rehabilitation, Department of Locomotor System Diseases University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mario","family":"Lando","sequence":"additional","affiliation":[{"name":"Hand Surgery and Microsurgery, Department of Locomotor System Diseases University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lorenzo","family":"Garagnani","sequence":"additional","affiliation":[{"name":"Hand Surgery and Microsurgery, Department of Locomotor System Diseases University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giovanni Luigi","family":"Di Gennaro","sequence":"additional","affiliation":[{"name":"Department of Paediatric Orthopaedics and Traumatology Rizzoli Orthopaedic Institute Bologna Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luciana","family":"Di Pancrazio","sequence":"additional","affiliation":[{"name":"Radiology, Diagnostic Imaging Services University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giorgia","family":"Bianconi","sequence":"additional","affiliation":[{"name":"Center for Clinical Psychology Services, Department of Mental Health University of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amira","family":"Elmakky","sequence":"additional","affiliation":[{"name":"Medical Genetics, Department of Medical and Surgical Sciences University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sergio","family":"Bernasconi","sequence":"additional","affiliation":[{"name":"Pediatrics, Department of Mother and Child University Hospital of Parma  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Landi","sequence":"additional","affiliation":[{"name":"Hand Surgery and Microsurgery, Department of Locomotor System Diseases University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Antonio","family":"Percesepe","sequence":"additional","affiliation":[{"name":"Medical Genetics, Department of Medical and Surgical Sciences University Hospital of Modena  Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2013,12,17]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1002\/ajmg.a.31304"},{"key":"e_1_2_6_3_1","doi-asserted-by":"publisher","DOI":"10.4055\/cios.2011.3.3.172"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1089\/gtmb.2009.0097"},{"key":"e_1_2_6_5_1","first-page":"331","article-title":"IFSSH.
