Screening of the entire coding and flanking sequences of the cystic fibrosis transmembrane conductance regulator (CFTR) gene in 64 males with CBAVD revealed that in only 23% CBAVD was caused by two CFTR mutations. The 5T allele in one copy, that causes reduced levels of the normal CFTR protein, in combination with a CFTR mutation in the other copy, was one of the most common causes of CBAVD. Twenty six per cent of men with CBAVD had the 5T allele. The presence of only one CFTR mutation or the 5T allele in 34% of patients suggests that undetected changes in CFTR may be involved in CBAVD. These molecular defects are probably mutations with partial penetrance. Moreover, the high proportion (20%) of patients with CBAVD who did not have CFTR mutations or the 5T allele allows to propose that another gene or genes could be responsible for CBAVD. In these cases, in vitro fertilization may be required and the genetic counselling appears to be very complex and additional studies, including CFTR mRNA and linkage analyses, are required to resolve these questions.</p>","PeriodicalId":7908,"journal":{"name":"Annales de genetique","volume":"40 1","pages":"5-9"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20098414","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}

In the absence of information, counseling as to the clinical significance and prognosis is difficult, especially in prenatal diagnosis. With the introduction of fluorescence in situ hybridization (FISH) marker identification has became feasible. However, FISH is relatively time-consuming and expensive. In an effort to overcome these disadvantages, we have used primed in situ labelling (PRINS) technique as an alternative. Presented here is one case in which PRINS was useful in rapidly identifying the origin of a marker chromosome detected on amniotic fluid chromosome analysis.

We describe two unrelated cases of homozygosity for inv(9) identified in amniocytes. In each case, both parents were heterozygotes for the inv(9); 46,XX,inv(9)(p11q13) and 46,XY,inv(9) (p11q13). Case 1 resulted in a normal term infant who at age 5 years was phenotypically and developmentally normal. Case 2 was referred for severe intrauterine growth retardation (IUGR) and oligohydramnios, and subsequently expired in utero. Even though inv(9) is a normal chromosome variant with a frequency of 1 to 3% in the general population, the finding of homozygosity for inv(9) and IUGR in this fetus suggested the possibility of uniparental disomy (UPD). Molecular studies confirmed the presence of both parental inv(9) chromosomes, excluding the possibility of chromosome 9 UPD as the cause of IUGR in this fetus. Presumably, inv(9) homozygosity results from the high frequency of inv(9) heterozygosity, and is a normal variant. However, until the effects of UPD for chromosome 9 are established, parental karyo types and, where appropriate, molecular studies should be performed to exclude UPD.
