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]

ACMG classification

Classification made for transcript

Verdict is Likely_benign. Variant got -2 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.3325231).
BS2
High AC in GnomAdExome4 at 11 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.

The c.2575G>A (p.D859N) alteration is located in exon 18 (coding exon 18) of the LGR4 gene. This alteration results from a G to A substitution at nucleotide position 2575, causing the aspartic acid (D) at amino acid position 859 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
