Beyond that, private supportive therapies based on the affected individual's needs may be considered. If exome sequencing is not diagnostic, exome array (when clinically available) can detect copy number variants, such as (multi)exon deletions or duplications that may not be identified by exome sequencing. old fashion trends that died .
