NettetIn X-linked dominant inheritance, the gene responsible for the disease is located on the X-chromosome, and the allele that causes the disease is dominant to the normal allele in females. Because females have twice as many X-chromosomes as males, females tend to be more frequently affected than males in the population. NettetThe most frequently used coding DNA reference sequences are the NM’s (RefSeq gene transcript sequences, e.g. NM_004006.2) and LRG’s (Locus Genomic Reference sequences, e.g. LRG_199t1). Variants Depending on the change found, the description of the variant can have many different formats.

http://ib.bioninja.com.au/higher-level/topic-10-genetics-and-evolu/102-inheritance/linked-genes.html Genetic linkage is the tendency of DNA sequences that are close together on a chromosome to be inherited together during the meiosis phase of sexual reproduction. Two genetic markers that are physically near to each other are unlikely to be separated onto different chromatids during chromosomal crossover, and are therefore said to be more linked than markers that are far apart. In other words, the nearer two genes are on a chromosome, the lower the chance of recombination between …
