Unraveling uniparental disomy

Chromosomes from one parent only: this is uniparental disomy (UPD)! Normally, every human has 22 pairs of chromosomes (called homologous chromosomes or homologs or autosomes) plus one couple of sexual chromosomes (which are two X chromosomes in females and one chromosome X plus one chromosome Y in males). For normal development, we need that, for

Robertsonian translocations: what to do?

If an exome or genome is being considered, this is where it should begin. Robertsonian translocations: what are they? Robertsonian translocations are chromosomal rearrangements involving two acrocentric chromosomes. Robertsonian translocations are actually the most frequent chromosomal rearrangements in humans, showing an incidence of 1 in 1,000. A difference between Robertsonian translocations and balanced translocations is

Balanced translocations: what to do?

If an exome or genome is being considered, this is where it should begin. Balanced reciprocal translocation: what to do? A balanced reciprocal translocation consists of reciprocal material exchange between two non-homologous chromosomes. Usually, balanced reciprocal translocations can be diagnosed by karyotype analysis (an example of translocation name within a karyotype report could be: 46,XX,t(12:18)(p12;q12.3),
