hg38_cytoband: GRCh38 Chromosome Cytobands

In GRIN2: Genomic Random Interval (GRIN)

GRCh38 Chromosome Cytobands

Description

This dataset contains the genomic coordinates of cytogenetic bands (cytobands) for the 22 autosomes and the X and Y chromosomes of the human GRCh38 (hg38) genome assembly. The dataset is primarily used by lsn.transcripts.plot to provide chromosome cytoband information for regional lesion and transcript visualization.

Usage

hg38_cytoband

Format

hg38_cytoband

A data frame with 1,549 rows and 5 columns:

chrom

Chromosome identifier (1-22, X, or Y).

chromStart

Start coordinate of the cytoband in base pairs, using the UCSC 0-based coordinate convention.

chromEnd

End coordinate of the cytoband in base pairs, using the UCSC end-exclusive coordinate convention.

name

Cytoband name (e.g., p11.1 or q22.3).

gieStain

Giemsa staining classification used for cytogenetic visualization (e.g., gneg, gpos, acen).
