Abstract

Uniparental disomy (UPD) describes the inheritance of both homologues of a pair of chromosomes from only one parent. This condition is often caused by nondisjunction events during meiosis. UPD has been reported as a rare cause of the autosomal recessive disorder and aberrant expression of imprinted genes that are expressed from only one parental allele, either maternal or paternal. Maternal and/or paternal UPD for chromosome 7 is the most frequently observed UPD after UPD15. Here we developed and validated, for the first time, an effective, CE-based method for a rapid and economic detection based on two-fluorescent STR multiplexes.
