Recently, in a study of over 5000 men, it has been determined that "something on chromosome 20", along with a particular variant of the androgen receptor gene, make men 7 TIMES MORE LIKELY TO GO BALD if they inherit both genes.
So what all genes are on this chromsome? Ive checked and will paste some of what is known about it
Chromosome 20 is one of the 23 pairs of chromosomes in humans. People normally have two copies of this chromosome. Chromosome 20 spans around 63 million base pairs (the building material of DNA) and represents between 2 and 2.5 percent of the total DNA in cells.
Identifying genes on each chromosome is an active area of genetic research. Because researchers use different approaches to predict the number of genes on each chromosome, the estimated number of genes varies. Chromosome 20 contains over 900 genes. New discoveries have recently linked this chromosome to the increasing suseptability to male-pattern baldness.
[edit] Genes
The following are some of the genes located on chromosome 20:
EDN3: endothelin 3
JAG1: jagged 1 (Alagille syndrome)
PANK2: pantothenate kinase 2 (Hallervorden-Spatz syndrome)
PRNP: prion protein (p27-30) (Creutzfeld-Jakob disease, Gerstmann-Strausler-Scheinker syndrome, fatal familial insomnia)
tTG:tissue transglutaminase (Celiac disease)
AHCY: S-adenosylhomocysteine hydrolase
ARFGEF2: ADP-ribosylation factor guanine nucleotide-exchange factor 2 (brefeldin A-inhibited)
GSS: glutathione synthetase
SALL4: sal-like 4 (Drosophila)
VAPB: VAMP (vesicle-associated membrane protein)-associated protein B and C
BMP2: Bone Morphogenetic Protein 2 (osteoblast differentiation)
[edit] Diseases & disorders
The following diseases are some of those related to genes on chromosome 20:
Adenosine deaminase deficiency
Alagille syndrome
Celiac disease
Maturity onset diabetes of the young type 1
Pantothenate kinase-associated neurodegeneration
Transmissible spongiform encephalopathy (prion diseases)
Waardenburg syndrome
