Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Inherited mutations in the CDKN2A/INK4a/MTS1 tumour suppressor gene on chromosome 9p21 are associated with familial predisposition to melanoma and other tumour types. Nonsense and missense mutations are also found in a variety of sporadic cancers, and over 140 sequence variants have already been recorded in the literature. In assessing the relevance of these variants and for counselling members of affected families, it is important to distinguish inactivating mutations from harmless polymorphisms. Existing functional assays have frequently reached conflicting conclusions and no single test appears adequate. Here we evaluate a number of alternatives including a novel assay based on retroviral delivery of p16INK4a cDNAs into human diploid fibroblasts. Among the 17 sequence variants analysed, three distinct categories can be distinguished: those that abrogate the binding of p16(INK4a) to CDK4 and CDK6, those that alter the properties of the protein without preventing it from interacting with CDKs, and those that have no discernible effect on protein function. These distinctions can be rationalized by considering the impact of the amino acid changes on the three-dimensional structure of the protein.
