Summary of Genes on Human Chromosomes

 
I've prepared a table of the number and types of gene on each human chromosome based on the data at the Ensembl site managed by the Wellcome Trust Sanger Institute in Cambridge UK.

The total number of genes comes to 26,290.

The different categories of gene are:

Known: The "known" protein-encoding genes are those for which there is solid full-length cDNA evidence that they are actually expressed.

Novel: The "novel" class is reserved for genes that are predicted but lack confirming evidence.

miRNA: Micro RNAs are short single-stranded RNAs that are thought to play a role in regulating gene expression.

snRNA: Small nuclear RNAs are required for a number of cellular processes such as RNA processing. Those required for splicing associate with proteins in the nucleus to form small nuclear ribonuleoprotein particles or "snurps."

rRNA: Ribosomal RNA forms the core of the ribosome.

snoRNA: Small nucleolar RNAs are required for proper processing of ribosomal RNA. The are located in the nucleolar region of the nucleus because that's where ribosomal RNA is made.

other RNA: The "other" category includes transfer RNA (tRNA) and some specialized RNAs such as 7SL RNA and P1 RNA.
