Genes affected
PEX1 (HGNC:8850): (peroxisomal biogenesis factor 1) This gene encodes a member of the AAA ATPase family, a large group of ATPases associated with diverse cellular activities. This protein is cytoplasmic but is often anchored to a peroxisomal membrane where it forms a heteromeric complex and plays a role in the import of proteins into peroxisomes and peroxisome biogenesis. Mutations in this gene have been associated with complementation group 1 peroxisomal disorders such as neonatal adrenoleukodystrophy, infantile Refsum disease, and Zellweger syndrome. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Sep 2013]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.95).
BP6
Variant 7-92518145-T-C is Benign according to our data. Variant chr7-92518145-T-C is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 285002.
BP7
Synonymous conserved (PhyloP=-1.86 with no splicing effect.
BS1
Variant frequency is greater than expected in population afr. GnomAd4 allele frequency = 0.00249 (379/152230) while in subpopulation AFR AF = 0.00855 (355/41534). AF 95% confidence interval is 0.00781. There are 2 homozygotes in GnomAd4. There are 185 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High Homozygotes in GnomAd4 at 2 AR gene
