Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NM_001378102.1(LRRC18):​c.20G>C​(p.Gly7Ala) variant causes a missense 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. 16/21 in silico tools predict a benign outcome for this variant. 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. G7V) has been classified as Likely benign.

• Frequency: Genomes: not found (cov: 33)
• Consequence: LRRC18 NM_001378102.1 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 0.169

Genes affected

LRRC18 (HGNC:23199): (leucine rich repeat containing 18) Predicted to be located in cytoplasm. [provided by Alliance of Genome Resources, Apr 2022]

WDFY4 (HGNC:29323): (WDFY family member 4) Predicted to be involved in autophagy. Predicted to act upstream of or within with a positive effect on CD8-positive, alpha-beta T cell activation. Predicted to act upstream of or within antigen processing and presentation and cellular response to virus. Predicted to be located in early endosome and endoplasmic reticulum. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000241577 (HGNC:):
