Use legacy APOC3 marker name

Description

Replace marker name APOC3 by the legacy name APOAI1 in a frequency database.

Usage

legacyAPO(db)

Arguments

Value

The modified database.

Built-in linkage maps

Description

Genetic maps for the autosomal STR markers featured in norSTR.

Usage

map51

map50

Format

map51 is a data frame with 51 rows and 4 columns: Marker, Chr, Mb, and cM.

map50 is a data frame with 50 rows and 4 columns: Marker, Chr, cM, and Kit.

Details

map51 is the current map and is recommended for new analyses. It provides both physical and genetic positions for 51 STR markers.

map50 is a legacy map retained for reproducibility of older analyses. It contains 50 markers and the genetic positions used in earlier versions of norSTR.

Compared with map50, map51 has the following changes:

• Added column Mb with the physical positions (GRCh38/hg38) of each marker, defined as the midpoint of each STR interval.

• Recalculated all genetic positions (cM) with ibdsim2::convertPos(), using the deCODE 2019 recombination map (Halldorsson et al., 2019).

• Added marker D6S1043.

• Renamed marker APOAI1 to APOC3. (This is an in-house marker not included in current commercial kits. The original name is a historical label and is no longer considered accurate.)

• Removed column Kit. Marker subsets corresponding to various commercial kits are available in markerSets.
