DNA copy number variations are important in the complex genetic architecture of müllerian disorders

Additional congenital abnormalities and regions of genomic imbalance are common in women with müllerian disorders, including MRKH. Recurrent microdeletions and microduplications associated with MRKH implicate specific possibly causative genes. The investigation of women with müllerian disorders should be thorough, and array CGH should be considered, given the potential highly significant familial implications of a chromosomal abnormality.
