Actually, some people with the genetic defect called aneuploidy can be a well fucntioning human. XXX syndrome (47, XXX) occurs when a female has an extra X chromosome, they function normally in everyday life. This is due to the X-inactivation gene present in all females that causes only one X chromosome to be active at a time, making any other X chromosome inside the cell inactive. XYY syndrome (47, XYY) is slightly different due to having an extra Y chromosome, men having this condition have an increase in velocity of growth from childhood but their average final height is close to the average normal height for males, so they don't really have any problems at all. Both syndromes are genetically different from the rest of the species but is phenotipically no different from them (humans normally have 46 chromosomes). There is also Turner's Syndrome (45, X) and Kleinfelter's Syndrome (47, XXY; can be phenotipically male, female, or intersex) but both actually impede on the normality in the life of a person.

And technically that wasn't in the molecular level, that was more of a chromosomal level. Molecular level would have you explain practically evertything at the level of molecules, in this case, one of the four macromolecules, nucleic acids (NA).
