Genes affected

PEX5L (HGNC:30024): (peroxisomal biogenesis factor 5 like) Enables peroxisome matrix targeting signal-1 binding activity and small GTPase binding activity. Predicted to be involved in protein import into peroxisome matrix, docking and regulation of cAMP-mediated signaling. Predicted to act upstream of or within maintenance of protein location and regulation of membrane potential. Located in cytosol. Part of receptor complex.

The c.130A>G (p.M44V) alteration is located in exon 3 (coding exon 3) of the PEX5L gene. This alteration results from a A to G substitution at nucleotide position 130, causing the methionine (M) at amino acid position 44 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
