Genes affected
AIF1 (HGNC:352): (allograft inflammatory factor 1) This gene encodes a protein that binds actin and calcium. This gene is induced by cytokines and interferon and may promote macrophage activation and growth of vascular smooth muscle cells and T-lymphocytes. Polymorphisms in this gene may be associated with systemic sclerosis. Alternative splicing results in multiple transcript variants, but the full-length and coding nature of some of these variants is not certain. [provided by RefSeq, Jan 2016]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.199C>T (p.P67S) alteration is located in exon 3 (coding exon 1) of the AIF1 gene. This alteration results from a C to T substitution at nucleotide position 199, causing the proline (P) at amino acid position 67 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
