She had hypotonia and large tongue, \u201ccoarse\u201d face, and umbilical hernia in presence of complex congenital cardiovascular malformations. In spite of normal neonatal screening we performed serum levels of thyroid hormones. Thyrotropin level was very high (&gt;50 \u03bcU\/ml; normal value 0.2\u20134 \u03bcU\/ml), while serum free T<jats:sub>3<\/jats:sub> (FT3) and free T<jats:sub>4<\/jats:sub> (FT4) levels were normal (FT3 3.6 pg\/ml, normal value 2.8\u20135.6 pg\/ml; FT4 11.6 pg\/ml, normal value 6.6\u201314 pg\/ml); antithyroid autoantibodies were absent. Thyroid scintigraphy with sodium 99m Tc pertechnetate showed a small ectopic thyroid located in sublingual position, so treatment with <jats:sc>L<\/jats:sc>\u2010thyroxine 37.5 \u03bcg\/24 hr was started with rapid improvement of the clinical picture. At 17 months of age the patient developed the complete characteristic phenotype of Williams syndrome (WS); the clinical diagnosis was proven by fluorescent in situ hybridization (FISH) analysis which showed hemizygous deletion of the <jats:italic>elastin<\/jats:italic> gene on chromosome 7. Recently a case of thyroid hemiagenesis in a child with WS has been reported; our patient underscores the association of hypothyroidism and WS. Moreover, our case shows that clinical manifestations of hypothyroidism may be present and the treatment may be necessary as it is in isolated congenital hypothyroidism. \u00a9 2004 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.a.20609","type":"journal-article","created":{"date-parts":[[2004,4,20]],"date-time":"2004-04-20T18:02:01Z","timestamp":1082484121000},"page":"183-185","source":"Crossref","is-referenced-by-count":14,"title":["New case of thyroid dysgenesis and clinical signs of hypothyroidism in Williams syndrome"],"prefix":"10.1002","volume":"127A","author":[{"given":"Rita","family":"Bini","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ivana","family":"Pela","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2004,1,23]]},"reference":[{"key":"e_1_2_4_2_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.61.6.608"},{"key":"e_1_2_4_3_1","doi-asserted-by":"publisher","DOI":"10.1002\/(SICI)1096-8628(19990827)85:5<491::AID-AJMG11>3.0.CO;2-Z"},{"key":"e_1_2_4_4_1","first-page":"59","volume-title":"Il bambino con sindrome di Williams","author":"Cappa M","year":"1994"},{"key":"e_1_2_4_5_1","doi-asserted-by":"publisher","DOI":"10.1093\/hmg\/8.10.1947"},{"key":"e_1_2_4_6_1","first-page":"1696","volume-title":"Nelson textbook of pediatrics","author":"LaFranchi S","year":"2000"},{"key":"e_1_2_4_7_1","doi-asserted-by":"publisher","DOI":"10.1136\/adc.81.3.198"},{"key":"e_1_2_4_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0022-3476(88)80272-5"},{"key":"e_1_2_4_9_1","first-page":"1156","article-title":"Deletions of the elastin gene at 7q11.23 occur in \u223c90% of patients with Williams syndrome","volume":"56","author":"Nickerson E","year":"1995","journal-title":"Am J Hum Genet"}],"container-title":["American Journal of Medical Genetics Part A"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1002%2Fajmg.a.20609","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/pdf\/10.1002\/ajmg.a.20609","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2023,10,18]],"date-time":"2023-10-18T03:48:30Z","timestamp":1697600910000},"score":1,"resource":{"primary":{"URL":"https:\/\/onlinelibrary.wiley.com\/doi\/10.1002\/ajmg.a.20609"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2004,1,23]]},"references-count":8,"journal-issue":{"issue":"2","published-print":{"date-parts":[[2004,6]]}},"alternative-id":["10.1002\/ajmg.a.20609"],"URL":"https:\/\/doi.org\/10.1002\/ajmg.a.20609","archive":["Portico"],"relation":{},"ISSN":["1552-4825","1552-4833"],"issn-type":[{"value":"1552-4825","type":"print"},{"value":"1552-4833","type":"electronic"}],"subject":[],"published":{"date-parts":[[2004,1,23]]}}}
