Abstract

Objective: We aimed to investigate the prevalence of Turner syndrome (TS) in the Ukrainian population, the frequency of karyotype variants, the age of children at diagnosis, the degree of short stature and phenotypic features in TS girls.Methods: A retrospective analysis was made in 538 TS girls aged 0.11-18.2years within the time period of 2005-2015 with detailed examination of 150 patients. Results:The prevalence of TS in Ukraine is 77.5 in 100.000 live female births.The average age at diagnosis is 9.33±4.93years.The relative proportions of karyotypic abnormalities found were: 45,X (59.3%); mosaicism 45,X/46,XX (22.9%); and structural abnormalities in chromosome X (17.8%).The most frequently encountered findings were growth delay (98.8%), shortening of the 4 th and 5 th metacarpal bones (74.6%), abnormal nails (73.3%), broad chest (60.7%), short neck (58.6%), hypertelorism of nipples (51.4%), malformations of the cardiovascular (19.6%) and urinary systems (13.8%) and pathology related to vision (20.1%) and hearing (22.0%).Conclusion: In the Ukrainian population, the highest proportion of patients with TS had a karyotype 45,X.TS was accompanied by a lower frequency of malformations of internal organs compared to other countries.

  • Peripheral lymphedema is thought to contribute to development of nail anomalies such as deeply set, narrow, and hyperconvex nails, affecting 19%-73% of individuals with TS.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
