Prenatal diagnosis rates of 47, XXX are increasing due to non\u2010invasive prenatal genetic testing. Previous studies suggest that prenatal diagnosed females have better neurodevelopmental outcomes. This cross\u2010sectional study describes diagnosis, physical features, medical problems, and neurodevelopmental features in a large cohort of females with 47, XXX. Evaluation included review of medical and developmental history, physical exam, cognitive, and adaptive testing. Medical and developmental features were compared between the prenatal and postnatal diagnosis groups using rate calculations and Fisher's exact test. Cognitive and adaptive tests scores were compared using t\u2010tests. Seventy\u2010four females age 6 months\u201324 years (mean 8.3 years) participated. Forty\u2010four (59.5%) females were in the prenatal diagnosis group. Mean age of postnatal diagnosis was 5.9 years; developmental delay was the most common indication for postnatal genetic testing. Common physical features included hypertelorism, epicanthal folds, clinodactyly, and hypotonia. Medical problems included dental disorders (44.4%), seizure disorders (16.2%), genitourinary malformations (12.2%). The prenatal diagnosis group had higher verbal (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.001), general ability index (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.004), and adaptive functioning scores (\n                      <jats:italic>P<\/jats:italic>\n                      \u2009&lt;\u20090.001). Rates of ADHD (52.2% vs. 45.5%,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20090.77) and learning disabilities (39.1% vs. 36.3%,\n                      <jats:italic>P<\/jats:italic>\n                      \u2009=\u20091.00) were similar between the two groups. These findings expand on the phenotypic features in females with Triple X syndrome and support that prenatally ascertained females have better cognitive and functional outcomes. However, prenatally diagnosed females are still at risk for neurodevelopmental disorders. Genetic counseling and treatment recommendations are summarized. \u00a9 2016 Wiley Periodicals, Inc.\n                    <\/jats:p>\n
