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]

Uncertain significance, criteria provided, single submitter	clinical testing	Labcorp Genetics (formerly Invitae), Labcorp	Aug 15, 2022	This sequence change creates a premature translational stop signal (p.Arg256*) in the PEX11B gene. While this is not anticipated to result in nonsense mediated decay, it is expected to disrupt the last 4 amino acid(s) of the PEX11B protein. This variant is present in population databases (rs782188850, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PEX11B-related conditions. ClinVar contains an entry for this variant (Variation ID: 596341). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -

This sequence change creates a premature translational stop signal (p.Arg256*) in the PEX11B gene. It is expected to disrupt the last 4 amino acid(s) of the PEX11B protein. This variant is present in population databases (rs782188850, gnomAD 0.02%). This variant has not been reported in the literature in individuals affected with PEX11B-related conditions and Iranom. The 14 years old boy whit mild intellectual disability and vision problem has been detected whit homozygous c.766C>T mutation on his PEX11B gene and the parents are first cousin. Therefore, it has been classified as a Variant of Pathogenic. -
