Hvor hyppigt det ses hos personer med en af genets tilstande, den hyppigste værdi på tværs af dem, sådan som Human Phenotype Ontology registrerer det. Disse sider beskriver egenskaber og den forskning, der ligger bag dem. De er ikke en diagnose, og hvis du har spørgsmål om symptomer, bør du spørge en læge eller genetisk rådgiver.
