  This issue includes six articles that develop and apply statistical methods
for the analysis of gene sequencing data of different types. The methods are
tailored to the different data types and, in each case, lead to biological
insights not readily identified without the use of statistical methods. A
common feature in all articles is the development of methods for analyzing
simultaneously data of different types (e.g., genotype, phenotype, pedigree,
etc.); that is, using data of one type to inform the analysis of data from
another type.
