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]

ACMG classification

Verdict is Likely_benign. Variant got -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.28).
• BP6: Variant 14-31561554-G-A is Benign according to our data. Variant chr14-31561554-G-A is described in ClinVar as [Likely_benign]. Clinvar id is 2992333.Status of the report is criteria_provided_single_submitter, 1 stars.
