title: A rare balanced nonrobertsonian translocation involving acrocentric chromosomes: Chromosome abnormality of t(13;15)(p11.2;q22.1).
abstract: BACKGROUND
  Balanced non-robertsonian translocation (RT), involving acrocentric chromosomes, is a rare event and only a few cases are reported. Most of the RTs are balanced involving acrocentric chromosomes with the breakpoints (q10;q10).
  
  
  METHODS
  Chromosome analysis was performed as per standard procedure - Giemsa-trypsin banding with 500 band resolution was analyzed for chromosome identification.
  
  
  RESULTS
  In the present study, we report a rare balanced non-RTs involving chromosomes 13 and 15 with cytogenetic finding of 46, XX, t(13;15) (p11.2;q22.1).
  
  
  CONCLUSIONS
  To the best of our knowledge, this is the first such report of an unusual non-RT of t(13:15) with (p11.2;q22.1) break points.
