Chromosome 1 is the designation for the largest human chromosome. Humans have two copies of chromosome 1, as they do with all of the autosomes, which are the non-sex chromosomes. Chromosome 1 spans about 249 million nucleotide base pairs, which are the basic units of information for DNA. [4] It represents about 8% of the total DNA in human ...

The median number of missense mutations in individual human genomes is about 8600, that is, two individuals differ by 1 in about 2600 amino acids or in about 20% of their proteins. The average individual has about 137 (predicted) loss of function mutations, including 71 frameshift and 148 in-frame deletions or insertions . [ 100 ]
•List of human protein-coding genes page 2 covers genes EPHA1–MTMR3 •List of human protein-coding genes page 3 covers genes MTMR4–SLC17A7 •List of human protein-coding genes page 4 covers genes SLC17A8–ZZZ3 NB: Each list page contains 5000 human protein-coding genes, sorted alphanumerically by the HGNC-approved gene symbol.
Furthermore, each mutation defines a set of specific Y chromosomes called a haplogroup. All humans carrying mutation A form a single haplogroup, and all humans carrying mutation B are part of this haplogroup, but mutation B also defines a more recent haplogroup (which is a subgroup or subclade) of its own to which humans carrying only mutation ...
1p36 deletion syndrome is caused by the deletion of the most distal light band of the short arm of chromosome 1. [5] Human chromosome 1. The breakpoints for 1p36 deletion syndrome have been variable and are most commonly found from 1p36.13 to 1p36.33. 40 percent of all breakpoints occur 3 to 5 million base pairs from the telomere. The size of ...

The three major single-chromosome mutations: deletion (1), duplication (2) and inversion (3). The two major two-chromosome mutations: insertion (1) and translocation (2). When the chromosome's structure is altered, this can take several forms: [16] Deletions: A portion of the chromosome is
