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]

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]

ACMG classification

Verdict is Uncertain_significance. Variant got 1 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.39525318).

The c.713A>G (p.Y238C) alteration is located in exon 4 (coding exon 3) of the TP53INP1 gene. This alteration results from a A to G substitution at nucleotide position 713, causing the tyrosine (Y) at amino acid position 238 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
