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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.22C>G (p.R8G) alteration is located in exon 1 (coding exon 1) of the LAMP1 gene. This alteration results from a C to G substitution at nucleotide position 22, causing the arginine (R) at amino acid position 8 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
