Genes affected

NUBPL (HGNC:20278): (NUBP iron-sulfur cluster assembly factor, mitochondrial) This gene encodes a member of the Mrp/NBP35 ATP-binding proteins family. The encoded protein is required for the assembly of the respiratory chain NADH dehydrogenase (complex I), an oligomeric enzymatic complex located in the inner mitochondrial membrane. Mutations in this gene cause mitochondrial complex I deficiency. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2014]

NUBPL Gene-Disease associations (from GenCC):

• mitochondrial complex I deficiency, nuclear type 21

  Inheritance: AR Classification: DEFINITIVE, STRONG Submitted by: G2P, Labcorp Genetics (formerly Invitae)
• Leigh syndrome

  Inheritance: AR Classification: MODERATE Submitted by: ClinGen
• mitochondrial complex I deficiency

  Inheritance: AR Classification: SUPPORTIVE Submitted by: Orphanet

ACMG classification

Our verdict: Benign. The variant received -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.59).
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.583 is higher than 0.05.
