Genomic DNA analyses demonstrated that two individuals were homozygous for different nonsense mutations (exon deletion or frameshift), and the third had a missense mutation encoding a nonfunctioning CHIP molecule.

In clinical testing laboratories a separate test has traditionally been used to detect exon CNVs, but this adds considerable time and cost, and is not available for all genes.

The human UFD1L gene was deleted in all 182 patients studied with 22q11 deletion, and a smaller deletion of approximately 20 kilobases that removed exons 1 to 3 ofUFD1L was found in one individual with features typical of 22q11 deletion syndrome.

If any one exon gets a debilitating mutation, the chain does not get built.

Alternatively, genetic methods can be used, typically involving Cre - recombinase (Cre)- mediated excision of a loxP flanked exon in Grin1, which encodes a critical NMDA - R subunit that is required for channel function.
