## Pseudoautosomal region base positions

### Description

Pseudoautosomal region (XTR, PAR1, PAR2) base positions for the X and Y chromsosomes from the GRCh36/hg18, GRCh37/hg19 and GRCh38/hg38 genome builds.

### Usage

    pseudoautosomal.hg18
    pseudoautosomal.hg19
    pseudoautosomal.hg38

### Format

A data.frame with the following columns.

`chrom`

  chromosome (X or Y)

`region`

  region (XTR, PAR1, or PAR2)

`start.base`

  starting base position of region

`end.base`

  ending base position of region

### Details

The XTR region on X is defined as DXS1217 to DXS3. The XTR region on Y is defined as SY20 to DXYS1.
