Genes affected

MBOAT4 (HGNC:32311): (membrane bound O-acyltransferase domain containing 4) Enables serine O-acyltransferase activity. Involved in peptidyl-serine octanoylation. Predicted to be located in endoplasmic reticulum. Predicted to be active in membrane. Predicted to be integral component of endoplasmic reticulum membrane. [provided by Alliance of Genome Resources, Apr 2022]

MBOAT4 links:

LEPROTL1 (HGNC:6555): (leptin receptor overlapping transcript like 1) Enables identical protein binding activity. Predicted to be involved in late endosome to vacuole transport via multivesicular body sorting pathway and negative regulation of growth hormone receptor signaling pathway. Predicted to be integral component of membrane. Predicted to be active in endosome. [provided by Alliance of Genome Resources, Apr 2022]

Ambry Genetics

Jul 19, 2023

This alteration is classified as likely benign based on a combination of the following: seen in unaffected individuals, population frequency, intact protein function, lack of segregation with disease, co-occurrence, RNA analysis, in silico models, amino acid conservation, lack of disease association in case-control studies, and/or the mechanism of disease or impacted region is inconsistent with a known cause of pathogenicity. -
