However, 60% to 70% of these cases do not receive a genetic diagnosis following microarray, and exome sequencing is being used more frequently in these cases with a reported diagnostic yield of approximately 10% to 30%. It is unknown whether this diagnostic yield is meaningful to patients and their families, given the risks and limitations such as discovering additional findings, limited ability t… Show more
