dbSNP rs370290813: LGALS1:p.Arg49Gly (chr22-37678538-C-G) – ACMG Classification: Likely_pathogenic (6 pts)

Variant summary

Our verdict is Likely pathogenic. The variant received 6 ACMG points: 6P and 0B. PM2PP3_Strong

The NM_002305.4(LGALS1):c.145C>G(p.Arg49Gly) variant causes a missense change. The variant allele was found at a frequency of 0.00000124 in 1,613,534 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a pathogenic outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R49C) has been classified as Uncertain significance.

Genes affected

LGALS1 (HGNC:6561): (galectin 1) The galectins are a family of beta-galactoside-binding proteins implicated in modulating cell-cell and cell-matrix interactions. This gene product may act as an autocrine negative growth factor that regulates cell proliferation. [provided by RefSeq, Jul 2008]
