Variant 13-113306497-G-A details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The ENST00000332556.5(LAMP1):c.74G>A(p.Cys25Tyr) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000222 in 1,613,912 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. C25W) has been classified as Uncertain significance.

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]

Ambry Genetics

Aug 02, 2022

The c.74G>A (p.C25Y) alteration is located in exon 2 (coding exon 2) of the LAMP1 gene. This alteration results from a G to A substitution at nucleotide position 74, causing the cysteine (C) at amino acid position 25 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
