• chr11-46895950-G-C

Variant summary

Our verdict is Uncertain significance. Variant got 3 ACMG points: 3P and 0B. PM2 PP2

The NM_002334.4(LRP4):​c.1117C>G​(p.Arg373Gly) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. 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. R373W) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: LRP4 NM_002334.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 3.41

Genes affected

LRP4 (HGNC:6696): (LDL receptor related protein 4) This gene encodes a member of the low-density lipoprotein receptor-related protein family. The encoded protein may be a regulator of Wnt signaling. Mutations in this gene are associated with Cenani-Lenz syndrome. [provided by RefSeq, May 2010]

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), LRP4. . Gene score misZ 3.0632 (greater than the threshold 3.09). Trascript score misZ 5.2056 (greater than threshold 3.09). GenCC has associacion of gene with postsynaptic congenital myasthenic syndrome, sclerosteosis, Cenani-Lenz syndactyly syndrome, sclerosteosis 2, congenital myasthenic syndrome 17.
