Genes affected

LAMP1 (HGNC:6499): (lysosomal associated membrane protein 1) The protein encoded by this gene is a member of a family of membrane glycoproteins. This glycoprotein provides selectins with carbohydrate ligands. It may also play a role in tumor cell metastasis. [provided by RefSeq, Jul 2008]

Jul 13, 2021

The c.582C>A (p.D194E) alteration is located in exon 5 (coding exon 5) of the LAMP1 gene. This alteration results from a C to A substitution at nucleotide position 582, causing the aspartic acid (D) at amino acid position 194 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
