✦ Synopsis

dbSNP is a general catalog of genetic polymorphism maintained by NCBI, mainly collating information for single nucleotide variations, many of which will be single nucleotide polymorphisms (SNPs), but also including small indels. It takes submissions from many sources, now also including large numbers of sequence variants identified by next-generation sequencing. A number of differently designed studies have attempted to estimate the error rates in data archived in dbSNP. Most recently, a study added to earlier studies identifying specific issues for duplicons and copy number variations (CNVs); earlier analyses have focused on stop codons, splice sites, and the general content of dbSNP. This article overviews dbSNP itself, these studies, and their implications. Hum Mutat 31:2-4, 2010.

## Abstract Detailed analysis of mechanisms of genetic loss for specific tumor suppressor genes (TSGs; e.g., __RB1, APC__ and __NF1__) indicates that TSG inactivation can occur by allelic loss of heterozygosity (LOH), without any alteration in DNA copy number. However, the role and prevalence of su
