Genes affected

TP53INP1 (HGNC:18022): (tumor protein p53 inducible nuclear protein 1) Predicted to enable antioxidant activity. Involved in autophagic cell death; positive regulation of autophagy; and positive regulation of transcription, DNA-templated. Located in autophagosome; cytosol; and nucleus. [provided by Alliance of Genome Resources, Apr 2022]

TP53INP1 links:

NDUFAF6 (HGNC:28625): (NADH:ubiquinone oxidoreductase complex assembly factor 6) This gene encodes a protein that localizes to mitochondria and contains a predicted phytoene synthase domain. The encoded protein plays an important role in the assembly of complex I (NADH-ubiquinone oxidoreductase) of the mitochondrial respiratory chain through regulation of subunit ND1 biogenesis. Mutations in this gene are associated with complex I enzymatic deficiency. [provided by RefSeq, Nov 2011]

Collection Method: clinical testing

The c.464G>A (p.S155N) alteration is located in exon 3 (coding exon 2) of the TP53INP1 gene. This alteration results from a G to A substitution at nucleotide position 464, causing the serine (S) at amino acid position 155 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
