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]
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]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2022The c.625G>T (p.A209S) alteration is located in exon 2 (coding exon 2) of the IFIT1B gene. This alteration results from a G to T substitution at nucleotide position 625, causing the alanine (A) at amino acid position 209 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
