- Aim: Regression testing practices in industry have to be better understood, both for the industry itself and for the research community. Method: We conducted a qualitative industry survey by i) running a focus group meeting with 15 industry participants and ii) validating the outcome in an on line questionnaire with 32 respondents. Results: Regression testing needs and practices vary greatly between and within organizations and at different stages of a project. The importance and challenges of automation is clear from the survey. Conclusions: Most of the findings are general testing issues and are not specific to regression testing. Challenges and good practices relate to test automation and testability issues.

- CONTEXT: Germline mutations in the MEN1 gene predispose to multiple endocrine neoplasia type 1 (MEN1) syndrome, but in up to 20-25% of clinical MEN1 cases, no MEN1 mutations can be found. Recently, a germline mutation in the CDKN1B gene, encoding p27(Kip1), was reported in one suspected MEN1 family with two acromegalic patients.OBJECTIVE: Our objective was to evaluate the role of CDKN1B/p27(Kip1) in human tumor predisposition in patients clinically suspected of MEN1 but testing negative for MEN1 germline mutation as well as in familial and sporadic acromegaly/pituitary adenoma patients.DESIGN: Genomic DNA was analyzed for germline mutations in the CDKN1B/p27(Kip1) gene by PCR amplification and direct sequencing.SETTING: The study was conducted at nonprofit academic research and medical centers.PATIENTS: Thirty-six Dutch and one German suspected MEN1 patient, who previously tested negative for germline MEN1 gene mutations, were analyzed. In addition, 19 familial and 50 sporadic acromegaly/pituitary adenoma patients from Europe and the United States were included in the study.MAIN OUTCOME MEASURES: We analyzed germline CDKN1B/p27(Kip1) mutations in individuals with pituitary adenoma and MEN1-like features.RESULTS: A heterozygous 19-bp duplication (c.59_77dup19) leading to a truncated protein product was identified in one Dutch patient with suspected MEN1 phenotype, pituitary adenoma, carcinoid tumor, and hyperparathyroidism (one of 36, 2.8%). No mutations were detected in either familial or sporadic acromegaly/pituitary adenoma patients.CONCLUSIONS: Our results support the previous finding that germline CDKN1B/p27(Kip1) mutations predispose to a human MEN1-like condition. However, such mutations appear uncommon in suspected MEN1 cases and rare or nonexistent in familial or sporadic acromegaly/pituitary adenoma patients.
