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 -9 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.013981968).
BP6
Variant 7-92517888-C-T is Benign according to our data. Variant chr7-92517888-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 167445.
BS1
Variant frequency is greater than expected in population mid. GnomAdExome4 allele frequency = 0.000112 (156/1395800) while in subpopulation MID AF = 0.0037 (20/5412). AF 95% confidence interval is 0.00245. There are 0 homozygotes in GnomAdExome4. There are 78 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.
