All three had characteristic findings on ultrasound and at birth. We also present a review of the literature, which suggests that a recognizable phenotype for this condition is emerging. Common findings on prenatal ultrasound include intrauterine growth restriction, ventriculomegaly, cleft lip or palate, and renal anomalies. These findings can provide a clue toward the prenatal diagnosis of this condition. There is also a clearly recognizable phenotype at birth. Facial characteristics include hypertelorism, broad nasal bridge\/bulbous or beaked nose, cleft lip\/palate, ear anomalies, and micrognathia. The exact extent of the isochromosome does not seem to predict severity, but mosaic cases are less severe, or at least have a greater probability of survival. \u00a9 2002 Wiley\u2010Liss, Inc.<\/jats:p>","DOI":"10.1002\/ajmg.b.10826","type":"journal-article","created":{"date-parts":[[2002,12,2]],"date-time":"2002-12-02T13:52:40Z","timestamp":1038837160000},"page":"375-380","source":"Crossref","is-referenced-by-count":35,"title":["Three cases of tetrasomy 9p"],"prefix":"10.1002","volume":"113","author":[{"given":"S.","family":"Dhandha","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"W.
