Twelve patients, 10 with a 45, X karyotype, 1 46 XXiq, and 1 mosaicism, have been given rhGH at a dosage of 0.15 U/kg per injection six times a week. Mean age at onset of treatment was 12.8, mean growth retardation was 4.1 SDS according to Sempé. After 18 months of treatment mean growth catch-up was 0.9 SDS. Maximal velocity was reach during the first trimester of treatment and decreased thereafter but was above normal for bone age in all but 2 after 18 months. The bone age increased less than structural age. No side effects were reported. At the present time the efficacy of rhGH in increasing final height in Turner's patients is likely but not demonstrated by any studies.

The psychomotor development of this child was considered as normal up to the age of 18 months; then, a delay in language development, behaviour disorders with an important instability interrupted by episodes of somnolence, were observed. This child was treated for psychotic disorders. At the age of 3 and half, he had two episodes of seizures associated with fever. He was hospitalized for a 24 hours coma (4 years old). An hepatomegaly and a dry, brittle hair were then observed. Hyperammonemia was made obvious by a protein tolerance test. The diagnosis of argininosuccinate lyase (ASAL) deficiency was based on the increased levels of ASA in plasma and urine. The deficiency was proved by a fibroblast culture. With protein restriction, hepatomegaly disappeared, hair became normal, the behaviour disorders and the delay in language development was improved. However, some school difficulties persist.

Three-fourths of these samples were taken because of advanced maternal age (greater than or equal to 35 years), whereas nearly one fifth were done to alleviate parental anxiety. The remainder were performed because of a precedent chromosomal anomaly in child or parent, to determine fetal sex in the case of X-linked familial disorders, or to obtain DNA for molecular analyses. Among the cytogenetic anomalies detected after 24 to 48 hours of culture, eight involved classical trisomies. In four other instances the chromosomal abnormalities were more difficult to interpret (mosaic trisomies 10, 13 and 15, an apparently uniform trisomy 7). All four were revealed to be \"false positives\", since neither the amniocenteses nor the karyotypes of the normal newborns (one pregnancy is still ongoing) confirmed an abnormal karyotype. In the case of the trisomy 7 we were able, after birth of the baby, to study two placental biopsies, one of which revealed an abnormality distinct from that detected in the chorionic villi. The observations concerning a fifth false positive are more worrisome, as an apparently uniform trisomy 18, with a fetus showing growth retardation on ultrasound, could not be confirmed in the abortus. Otherwise, we have not encountered a false negative result. In this article we discuss the mechanisms potentially responsible for the cytogenetic discrepancies sometimes observed between fetal and placental tissues. Molecular analyses may help to establish whether a chromosomal anomaly present in fetal chorionic villi had its origin in the pre- or post-zygotic stage; in the latter case the aneuploidy may be uniquely extrafetal.</p>","PeriodicalId":75984,"journal":{"name":"Journal de genetique humaine","volume":"37 1","pages":"61-9"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13856021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
