• chr1-2406766-G-C

Variant summary

Our verdict is Uncertain significance. Variant got 4 ACMG points: 4P and 0B. PM1 PM2

The NM_002617.4(PEX10):​c.730C>G​(p.Arg244Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R244P) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 34)
• Consequence: PEX10 NM_002617.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 2.27

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]

PEX10 (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 4 ACMG points.

• PM1: In a topological_domain Cytoplasmic (size 89) in uniprot entity PEX10_HUMAN there are 8 pathogenic changes around while only 2 benign (80%) in NM_002617.4
• PM2: Very rare variant in population databases, with high coverage
