Patient, Clinical Phenotype,and PEX26 Allele | PEX26 Mutation in cDNA | Comment |
PBD059: | ||
ZS: | ||
T77fs139X homozygote | c.230+1G→T | This donor splice-site mutation results in the insertion of 173, 236, or 650 bp of intron 2, with the result of addition of a nonspecific sequence of 61 or 82 aa. For clarity, we designate the allele by the shortest insert. |

PBD055: | ||
IRD: | ||
[L153V+R288fs366X] | [c.457C→G+c.862delC] | Nonspecific sequence of 78 aa; L153V and R288fs366C are in cis. |
