My wife is pregnant.  5th month anomaly scan showed nuchal fold thickness 6.4 mm and doctor asked to do amniocentesis.  The scan showed no other abnormalities in the child.  We performed micro array testing and whole exome sequencing.  The micro array report reads as follows "The cytogenomic microarray analysis showed a loss involving chromosome 13q14.11q14.2 (3.8 MB), indicating deletion in this region. This deletion contains 44 genes. This deletion does not contain RB1 gene which is the critical gene in  this region. Since the deletion has not been reported previously, the above copy number variant is classified as Uncertain Significance" but the whole exome report says "No reportable sequence variants or copy number variants (CNV) related to phenotype detected".  What should be learned from these two reports? Is micro array test or whole exome sequencing more reliable?
