The reported frequency and the types of these associated anomalies vary between different studies. The purpose of this investigation was to assess the frequency and the types of associated anomalies among cases with an/microphthalmia in a geographically well defined population of northeastern France of 387,067 consecutive pregnancies from 1979 to 2007. Of the 98 infants with an/microphthalmia born during this period (prevalence at birth of 2.53 per 10,000), 88.8 % had associated anomalies. Cases with associated anomalies were divided into recognizable conditions (25 (25.5%) cases with chromosomal and 17 (17.3%) cases with non chromosomal conditions), and non recognizable conditions (45–45.9%- cases with multiple congenital anomalies –MCA). Trisomy 13 and trisomy 18 were the most frequent chromosomal abnormalities. Amniotic bands sequence, oculo-auriculo-vertebral spectrum, CHARGE syndrome and VACTERL association were most often present in recognizable non chromosomal conditions. Anomalies in the musculoskeletal, cardiovascular and central nervous systems were the most common other anomalies in cases with MCA and non recognizable conditions. However, given the limitation of the limited numbers of cases there should be urging caution in interpreting these results. In conclusion the frequency of associated anomalies in infants with anophthalmia and microphthalmia emphasizes the need for a thorough investigation of these cases. Routine screening for other anomalies especially musculoskeletal, cardiac and central nervous systems anomalies may need to be considered in infants with anophthalmia and microphthalmia, and referral of these cases for genetic counselling seems warranty.</p></div>","PeriodicalId":11916,"journal":{"name":"European journal of medical genetics","volume":"67 ","pages":"Article 104892"},"PeriodicalIF":1.9,"publicationDate":"2023-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S1769721223001982/pdfft?md5=cbbb1e5ccfb2f35826c3ed31b9d6f4f4&pid=1-s2.0-S1769721223001982-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138679749","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
