Variant summary

Our verdict is Likely benign. The variant received -3 ACMG points: 2P and 5B. PM2 BP4_Strong BP7

The NM_018490.5(LGR4):​c.2589G>T​(p.Ser863Ser) variant causes a synonymous change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Synonymous variant affecting the same amino acid position (i.e. S863S) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: LGR4 NM_018490.5 synonymous
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -3.86
• Publications: 2 publications found

Genes affected

LGR4 (HGNC:13299): (leucine rich repeat containing G protein-coupled receptor 4) The protein encoded by this gene is a G-protein coupled receptor that binds R-spondins and activates the Wnt signaling pathway. This Wnt signaling pathway activation is necessary for proper development of many organs of the body. [provided by RefSeq, Oct 2016]

LGR4 Gene-Disease associations (from GenCC):

• delayed puberty, self-limited

  Inheritance: Unknown Classification: LIMITED Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Likely_benign. The variant received -3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.62).
• BP7: Synonymous conserved (PhyloP=-3.86 with no splicing effect.
