Test to check DNA flaws in prospective parents

It is important to remember that only 600 of the better known conditions would be examined here. The test would miss many rarer chromosomal disorders affecting 1 in 200 of us. Tiny but equally 'catastrophic' genetic variants are being identified as culprits for previously unexplained learning disabilities in individuals. The mystery is that, in some cases, controls can share the same genetic variants without adverse effects. We still have a long way to go before genetic research can explain these differences. Strict guidelines need to be followed so that conditions tested for will definitely result in either very early death or severe suffering.
