Zellweger's Syndrome Though the peroxisome is a small organelle, defects in it are extremely serious and can cause a host of physiological problems. ... Yik et al (2009) tabulated deleterious alleles for PEX1, including twelve new deleterious mutations (seven frameshift, one nonsense, and four splice junction), in addition to eight previously reported deleterious mutations (three frameshift, two nonsense, one in-frame duplication, one in-frame deletion, and one splice junction) that resulted in shortened and non-functional PEX1 proteins. ...

Unequal crossing over during meiosis can lead to duplications of genetic material; this can have a large impact if the reading frame is disrupted. ... If, as a result of the point mutation or partial deletion, the reading frame is shifted, the consequence is that entirely different codons, specifying different amino acids are produced after the mutation. ... This proposed that the Duchenne form of the disease involved the disruption of the reading frame, and therefore there is a complete absence of the dystrophin in the patient. ...
