Genes affected

IFIT2 (HGNC:5409): (interferon induced protein with tetratricopeptide repeats 2) Enables RNA binding activity. Involved in negative regulation of protein binding activity; positive regulation of apoptotic process; and response to virus. Located in endoplasmic reticulum.

LIPA (HGNC:):

LIPA 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]

Mar 28, 2023

The c.838A>G (p.N280D) alteration is located in exon 2 (coding exon 2) of the IFIT2 gene. This alteration results from a A to G substitution at nucleotide position 838, causing the asparagine (N) at amino acid position 280 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
