Variants pathogenicity by type

Statistics on ClinVar variants can assist in determining whether a specific variant type in the PEX6 gene is commonly pathogenic or not.

In the table, we include only reliable ClinVar variants with their consequences to MANE Select, Mane Plus Clinical transcripts, or transcripts with TSL equals 1. Click the count to view the source variants.

Warning: slight differences between displayed counts and the number of variants in ClinVar may occur, primarily due to (1) the application of a different transcript and/or consequence by our variant effect predictor or (2) differences in clinical significance: we classify Benign/Likely benign variants as Likely benign and Pathogenic/Likely pathogenic variants as Likely pathogenic.

• Function: FUNCTION: Involved in peroxisome biosynthesis. Required for stability of the PTS1 receptor. Anchored by PEX26 to peroxisome membranes, possibly to form heteromeric AAA ATPase complexes required for the import of proteins into peroxisomes.
• Disease: DISEASE: Peroxisome biogenesis disorder 4A (PBD4A) [MIM:614862]: A fatal peroxisome biogenesis disorder belonging to the Zellweger disease spectrum and clinically characterized by severe neurologic dysfunction with profound psychomotor retardation, severe hypotonia and neonatal seizures, craniofacial abnormalities, liver dysfunction, and biochemically by the absence of peroxisomes. Additional features include cardiovascular and skeletal defects, renal cysts, ocular abnormalities, and hearing impairment. Most severely affected individuals with the classic form of the disease (classic Zellweger syndrome) die within the first year of life. {ECO:0000269|PubMed:10408779, ECO:0000269|PubMed:8670792}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Peroxisome biogenesis disorder 4B (PBD4B) [MIM:614863]: A peroxisome biogenesis disorder that includes neonatal adrenoleukodystrophy (NALD) and infantile Refsum disease (IRD), two milder manifestations of the Zellweger disease spectrum. The clinical course of patients with the NALD and IRD presentation is variable and may include developmental delay, hypotonia, liver dysfunction, sensorineural hearing loss, retinal dystrophy and vision impairment. Children with the NALD presentation may reach their teens, while patients with the IRD presentation may reach adulthood. The clinical conditions are often slowly progressive in particular with respect to loss of hearing and vision. The biochemical abnormalities include accumulation of phytanic acid, very long chain fatty acids (VLCFA), di- and trihydroxycholestanoic acid and pipecolic acid. {ECO:0000269|PubMed:11355018}. Note=The disease is caused by mutations affecting the gene represented in this entry.; DISEASE: Heimler syndrome 2 (HMLR2) [MIM:616617]: A form of Heimler syndrome, a very mild peroxisome biogenesis disorder characterized by sensorineural hearing loss, amelogenesis imperfecta resulting in enamel hyoplasia of the secondary dentition, nail defects, and occasional or late-onset retinal pigmentation abnormalities. {ECO:0000269|PubMed:19105186, ECO:0000269|PubMed:26387595, ECO:0000269|PubMed:27302843}. Note=The disease is caused by mutations affecting the gene represented in this entry.
