Genes affected

GPR119 (HGNC:19060): (G protein-coupled receptor 119) This gene encodes a member of the rhodopsin subfamily of G-protein-coupled receptors that is expressed in the pancreas and gastrointestinal tract. The encoded protein is activated by lipid amides including lysophosphatidylcholine and oleoylethanolamide and may be involved in glucose homeostasis. This protein is a potential drug target in the treatment of type 2 diabetes.[provided by RefSeq, Jan 2010]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.004087627).
• BP6: Variant X-130384522-G-A is Benign according to our data. Variant chrX-130384522-G-A is described in ClinVar as [Benign]. Clinvar id is 780736.Status of the report is criteria_provided_single_submitter, 1 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.0074 (831/112296) while in subpopulation AFR AF= 0.0257 (794/30936). AF 95% confidence interval is 0.0242. There are 10 homozygotes in gnomad4. There are 187 alleles in male gnomad4 subpopulation. Median coverage is 23. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd at 10 gene
