Genes affected

PEX11B (HGNC:8853): (peroxisomal biogenesis factor 11 beta) The protein encoded by this gene facilitates peroxisomal proliferation and interacts with PEX19. The encoded protein is found in the peroxisomal membrane. Several transcript variants, some protein-coding and some not protein-coding, have been found for this gene. [provided by RefSeq, Dec 2012]

ACMG classification

Verdict is Pathogenic. Variant got 14 ACMG points.

• PVS1: Loss of function variant, product does not undergo nonsense mediated mRNA decay. Variant is located in the 3'-most 50 bp of the penultimate exon, not predicted to undergo nonsense mediated mRNA decay. There are 4 pathogenic variants in the truncated region.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 1-145916914-G-A is Pathogenic according to our data. Variant chr1-145916914-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 453306.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
