The sum of the number of unique genes and the number of gene families is an estimate of the number of types of genes.

The minimum size of the proteome can be estimatedfrom the number of types of genes.

Genes are not uniformly distributed in the genome.

Regions longer than 500 kb where there are no ORFs called as deserts

The most gene-rich chromosomes have 10% of their sequences as deserts. So overall, 20% of the human genome consists of deserts that have no protein coding genes.
