Genes affected
AIFM2 (HGNC:21411): (apoptosis inducing factor mitochondria associated 2) This gene encodes a flavoprotein oxidoreductase that binds single stranded DNA and is thought to contribute to apoptosis in the presence of bacterial and viral DNA. The expression of this gene is also found to be induced by tumor suppressor protein p53 in colon cancer cells. [provided by RefSeq, Nov 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 02, 2023The c.758G>A (p.R253H) alteration is located in exon 7 (coding exon 6) of the AIFM2 gene. This alteration results from a G to A substitution at nucleotide position 758, causing the arginine (R) at amino acid position 253 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
