q14q22

q14q22 refers to a specific chromosomal region. Chromosomes are structures found within the nucleus of cells that are made up of DNA and proteins. They carry genetic information in the form of genes. Humans typically have 23 pairs of chromosomes, 22 pairs of autosomes and one pair of sex chromosomes. The notation q14q22 indicates a segment on the long arm (denoted by 'q') of a chromosome. The numbers 14 and 22 refer to specific bands and sub-bands within that arm. For example, q14 would represent band 14 on the q arm, and q22 would represent sub-band 22 within band 2 of the q arm. Therefore, q14q22 denotes a region that spans from band 14 to band 22 on the long arm of a particular chromosome. The specific chromosome is usually indicated by a number preceding the 'q', such as 14q14q22. Alterations or rearrangements within this region can be associated with various genetic conditions or developmental abnormalities. Geneticists use this standardized nomenclature to precisely identify locations on chromosomes for research and clinical diagnosis.
