Genes affected

PEX11A (HGNC:8852): (peroxisomal biogenesis factor 11 alpha) This gene is a member of the PEX11 family, which is composed of membrane elongation factors involved in regulation of peroxisome maintenance and proliferation. This gene product interacts with peroxisomal membrane protein 19 and may respond to outside stimuli to increase peroxisome abundance. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. [provided by RefSeq, Oct 2012]

PEX11A (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.2590184).

The c.473A>T (p.K158I) alteration is located in exon 3 (coding exon 3) of the PEX11A gene. This alteration results from a A to T substitution at nucleotide position 473, causing the lysine (K) at amino acid position 158 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
