Heteromorphism

Heteromorphism

Repeated DNA sequences in the genome are subject to heteromorphism. Chromosomal heteromorphisms are structural chromosomal variants that are widespread in human populations and have no known effect on phenotype. These heteromorphic regions may be identified by several methods; each of these methods reveals a typical staining pattern implying constitutional differences in heterochromatin. Common chromosomal polymorphisms detected by Giemsa banding are considered as heteromorphisms and include heterochromatin regions on short arms of Acrocentric chromosomes and regions of chromosomes 1, 9, 16 and Y. Impact of chromosome heteromorphism has been studied previously on infertility and recurrent miscarriages. There seems an increased incidence of chromosome heteromorphism in infertility and recurrent miscarriages; however, the underlined mechanism needs to be clearly defined yet.

Impact factor is a measure reflecting the average number of citations to recent articles published in the journal. The impact of the journal is influenced by impact factor, the journals with high impact factor are considered more important than those with lower ones. This information can be published in our peer reviewed journal with impact factors and are calculated using citations not only from research articles but also review articles (which tend to receive more citations), editorials, letters, meeting abstracts, short communications, and case reports.
