Genes affected

PEX10 (HGNC:8851): (peroxisomal biogenesis factor 10) This gene encodes a protein involved in import of peroxisomal matrix proteins. This protein localizes to the peroxisomal membrane. Mutations in this gene result in phenotypes within the Zellweger spectrum of peroxisomal biogenesis disorders, ranging from neonatal adrenoleukodystrophy to Zellweger syndrome. Alternative splicing results in two transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Submissions by phenotype

not specified Benign:3

Likely benign, no assertion criteria provided	clinical testing	Genetic Services Laboratory, University of Chicago	-	Likely benign based on allele frequency in 1000 Genomes Project or ESP global frequency and its presence in a patient with a rare or unrelated disease phenotype. NOT Sanger confirmed. -
Benign, criteria provided, single submitter	clinical testing	Women's Health and Genetics/Laboratory Corporation of America, LabCorp	Oct 09, 2017	Variant summary: The PEX10 c.291A>G (p.Thr97Thr) variant involves the alteration of a non-conserved nucleotide, resulting in a synonymous change located in the Pex, N-terminal domain(IPR006845) (InterPro). One in silico tool predicts a benign outcome for this variant. 4/5 splice prediction tools predict no significant impact on normal splicing. ESE finder predicts that this variant may affect ESE sites. However, these predictions have yet to be confirmed by functional studies. This variant was found in 212895/276368 control chromosomes (82611 homozygotes) (gnomAD) at a frequency of 0.7703316, indicating this variant is the major allele. In addition, multiple clinical diagnostic laboratories/reputable databases classified this variant as benign/likely benign. Taken together, this variant is classified as benign. -

Benign, no assertion criteria provided	clinical testing	Mayo Clinic Laboratories, Mayo Clinic	Oct 21, 2015	- -
Benign, criteria provided, single submitter	clinical testing	GeneDx	Jun 13, 2018	This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease. -

Peroxisome biogenesis disorder 6A (Zellweger) Benign:2

Benign, criteria provided, single submitter	clinical testing	Genome-Nilou Lab	Jul 08, 2021	- -
Benign, criteria provided, single submitter	clinical testing	Illumina Laboratory Services, Illumina	Jan 13, 2018	This variant was observed in the ICSL laboratory as part of a predisposition screen in an ostensibly healthy population. It had not been previously curated by ICSL or reported in the Human Gene Mutation Database (HGMD: prior to June 1st, 2018), and was therefore a candidate for classification through an automated scoring system. Utilizing variant allele frequency, disease prevalence and penetrance estimates, and inheritance mode, an automated score was calculated to assess if this variant is too frequent to cause the disease. Based on the score and internal cut-off values, a variant classified as benign is not then subjected to further curation. The score for this variant resulted in a classification of benign for this disease. -
