Genes affected

IFIT3 (HGNC:5411): (interferon induced protein with tetratricopeptide repeats 3) Enables identical protein binding activity. Involved in negative regulation of apoptotic process; negative regulation of cell population proliferation; and response to virus. Located in cytosol and mitochondrion. [provided by Alliance of Genome Resources, Apr 2022]

IFIT3 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 22, 2023

The c.1016T>C (p.L339P) alteration is located in exon 2 (coding exon 2) of the IFIT3 gene. This alteration results from a T to C substitution at nucleotide position 1016, causing the leucine (L) at amino acid position 339 to be replaced by a proline (P). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
