Genes affected

NDUFA13 (HGNC:17194): (NADH:ubiquinone oxidoreductase subunit A13) This gene encodes a subunit of the mitochondrial membrane respiratory chain NADH dehydrogenase (Complex I), which functions in the transfer of electrons from NADH to the respiratory chain. The protein is required for complex I assembly and electron transfer activity. The protein binds the signal transducers and activators of transcription 3 (STAT3) transcription factor, and can function as a tumor suppressor. The human protein purified from mitochondria migrates at approximately 16 kDa. Transcripts originating from an upstream promoter and capable of expressing a protein with a longer N-terminus have been found, but their biological validity has not been determined.

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 5 ACMG points.

PVS1

Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.24597701 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.

PP5

Variant 19-19516333-G-A is Pathogenic according to our data. Variant chr19-19516333-G-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 2671946.Status of the report is criteria_provided_single_submitter, 1 stars.

BS2

High AC in GnomAd4 at 7 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
