Genes affected

M6PR (HGNC:6752): (mannose-6-phosphate receptor, cation dependent) This gene encodes a member of the P-type lectin family. P-type lectins play a critical role in lysosome function through the specific transport of mannose-6-phosphate-containing acid hydrolases from the Golgi complex to lysosomes. The encoded protein functions as a homodimer and requires divalent cations for ligand binding. Alternatively spliced transcript variants encoding multiple isoforms have been observed for this gene. A pseudogene of this gene is located on the long arm of chromosome X. [provided by RefSeq, May 2011]

The c.796G>A (p.E266K) alteration is located in exon 7 (coding exon 6) of the M6PR gene. This alteration results from a G to A substitution at nucleotide position 796, causing the glutamic acid (E) at amino acid position 266 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
