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.[1] It represents about 9% of the total DNA in human cells.[2]
Identifying genes on each chromosome is an active area of genetic research. Chromosome 1 is currently thought to have 4,316 genes, exceeding previous predictions based on its size.[1] It was the last completed chromosome, sequenced two decades after the beginning of the Human Genome Project.
Genes
The following are some of the genes located on chromosome 1:
p-arm
- ACADM: acyl-Coenzyme A dehydrogenase, C-4 to C-12 straight chain

According to http://www.ornl.gov/sci/techresources/Human_Genome/posters/chromosome/chromo01.shtml the Chromosome 1 contains 263 million base pairs
Diseases & disorders
There are 890 known diseases related to this chromosome. Some of these diseases are deafness, Alzheimer disease, glaucoma and breast cancer. Rearrangements and mutations of chromosome 1 are prevalent in cancer and many other diseases. Patterns of sequence variation reveal signals of recent selection in specific genes that may contribute to human fitness, and also in regions where no function is evident. The following diseases are some of those related to genes on chromosome 1 (which contains the most known genetic diseases of any human chromosome):
- 1q21.1 deletion syndrome
- 1q21.1 duplication syndrome
- Alzheimer disease
- Alzheimer disease, type 4
- Breast cancer
- Brooke Greenberg Disease (Syndrome X)
- Carnitine palmitoyltransferase II deficiency
- Charcot–Marie–Tooth disease, types 1 and 2
- collagenopathy, types II and XI
- congenital hypothyroidism
- Deafness, autosomal recessive deafness 36
- Ehlers-Danlos syndrome
- Ehlers-Danlos syndrome, kyphoscoliosis type
- Factor V Leiden thrombophilia
- Familial adenomatous polyposis
- galactosemia
- Gaucher disease
- Gaucher disease type 1
- Gaucher disease type 2
- Gaucher disease type 3
- Gaucher-like disease
- Gelatinous drop-like corneal dystrophy
- Glaucoma
- Hemochromatosis
- Hemochromatosis, type 2
- Hepatoerythropoietic porphyria
- Homocystinuria
- Hutchinson Gilford Progeria Syndrome
- 3-hydroxy-3-methylglutaryl-CoA lyase deficiency
- Hypertrophic cardiomyopathy, autosomal dominant mutations of TNNT2; hypertrophy usually mild; restrictive phenotype may be present; may carry high risk of sudden cardiac death
- maple syrup urine disease
- medium-chain acyl-coenzyme A dehydrogenase deficiency
- Microcephaly
- Muckle-Wells Syndrome
- Nonsyndromic deafness
- Nonsyndromic deafness, autosomal dominant
- Nonsyndromic deafness, autosomal recessive
