Genes affected

IFIT1B (HGNC:23442): (interferon induced protein with tetratricopeptide repeats 1B) Predicted to enable RNA binding activity. Predicted to be involved in defense response to virus. Predicted to act upstream of or within cellular response to interferon-alpha; cellular response to interferon-beta; and response to bacterium. Predicted to be located in cytoplasm. Predicted to be active in cytosol. [provided by Alliance of Genome Resources, Apr 2022]

IFIT1B links:

LIPA (HGNC:6617): (lipase A, lysosomal acid type) This gene encodes lipase A, the lysosomal acid lipase (also known as cholesterol ester hydrolase). This enzyme functions in the lysosome to catalyze the hydrolysis of cholesteryl esters and triglycerides. Mutations in this gene can result in Wolman disease and cholesteryl ester storage disease. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jan 2014]

Ambry Genetics

Jun 13, 2024

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. -
