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]

The c.341A>T (p.Q114L) alteration is located in exon 3 (coding exon 3) of the LAMP1 gene. This alteration results from a A to T substitution at nucleotide position 341, causing the glutamine (Q) at amino acid position 114 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
