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 Benign. Variant got -19 ACMG points.

• 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.
• BP4: Computational evidence support a benign effect (MetaRNN=0.0016334653).
• BP6: Variant 11-46896317-A-G is Benign according to our data. Variant chr11-46896317-A-G is described in ClinVar as [Likely_benign]. Clinvar id is 304892.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr11-46896317-A-G is described in Lovd as [Likely_benign].
• BA1: GnomAd4 highest subpopulation (AFR) allele frequency at 95% confidence interval = 0.174 is higher than 0.05.
