Variant summary

Our verdict is Likely benign. Variant got -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The NR_003228.1(AFG3L1P):​n.666-250G>C variant causes a intron, non coding transcript change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: not found (cov: 32)
• Consequence: AFG3L1P NR_003228.1 intron, non_coding_transcript
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -0.106

Genes affected

AFG3L1P (HGNC:314): (AFG3 like matrix AAA peptidase subunit 1, pseudogene) Predicted to be involved in protein processing. Predicted to act upstream of or within cristae formation; mitochondrial fusion; and mitochondrial protein processing. Predicted to be located in mitochondrial inner membrane. Predicted to be part of m-AAA complex. [provided by Alliance of Genome Resources, Apr 2022]
