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.194T>C (p.F65S) alteration is located in exon 3 (coding exon 3) of the LAMP1 gene. This alteration results from a T to C substitution at nucleotide position 194, causing the phenylalanine (F) at amino acid position 65 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
