Genes affected

MBOAT7 (HGNC:15505): (membrane bound O-acyltransferase domain containing 7) This gene encodes a member of the membrane-bound O-acyltransferases family of integral membrane proteins that have acyltransferase activity. The encoded protein is a lysophosphatidylinositol acyltransferase that has specificity for arachidonoyl-CoA as an acyl donor. This protein is involved in the reacylation of phospholipids as part of the phospholipid remodeling pathway known as the Land cycle. Alternative splicing results in multiple transcript variants.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 1 ACMG points.

PM2

Very rare variant in population databases, with high coverage;

BS1

Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000609 (89/1461076) while in subpopulation SAS AF= 0.000487 (42/86166). AF 95% confidence interval is 0.00037. There are 1 homozygotes in gnomad4_exome. There are 58 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck. Existence of Clinvar submissions makes me limit the strength of this signal to Supporting
