Genetic Variant NM_013437.5:c.2168G>A (chr8-104491085-C-T) – ACMG Classification: Likely_benign (-6 pts)

Variant summary

Our verdict is Likely benign. Variant got -6 ACMG points: 0P and 6B. BP4_ModerateBS2

The NM_013437.5(LRP12):c.2168G>A(p.Arg723His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000638 in 1,614,120 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 (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R723C) 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 c.2168G>A (p.R723H) alteration is located in exon 7 (coding exon 7) of the LRP12 gene. This alteration results from a G to A substitution at nucleotide position 2168, causing the arginine (R) at amino acid position 723 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
