Genetic Variant LRP12:p.Arg723Cys (chr8-104491086-G-A) – ACMG Classification: Uncertain_significance (0 pts)

Variant summary

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

The NM_013437.5(LRP12):c.2167C>T(p.Arg723Cys) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00000205 in 1,461,876 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R723H) has been classified as Uncertain significance.

Genes affected

LRP12 (HGNC:31708): (LDL receptor related protein 12) This gene encodes a member of the low-density lipoprotein receptor related protein family. The product of this gene is a transmembrane protein that is differentially expressed in many cancer cells. Alternate splicing results in multiple transcript variants. [provided by RefSeq, Feb 2010]

The LRP12 c.2167C>T variant is predicted to result in the amino acid substitution p.Arg723Cys. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0029% of alleles in individuals of Latino descent in gnomAD. To date, most pathogenic variants in LRP12 are repeat expansions in the 5' UTR. At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. -
