Genes affected

AFG1L (HGNC:16411): (AFG1 like ATPase) This gene encodes a mitochondrial integral membrane protein that plays a role in mitochondrial protein homeostasis. The protein contains a P-loop motif and a five-domain structure that is conserved in fly, yeast, and bacteria. It functions to mediate the degradation of nuclear-encoded complex IV subunits. Two conserved estrogen receptor binding sites are located within 2.5 kb of this gene. Polymorphisms in this gene have been associated with bipolar disorder. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Apr 2016]

ACMG classification

Our verdict: Likely_benign. The variant received -4 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.046323746).
• BP6: Variant 6-108323851-A-G is Benign according to our data. Variant chr6-108323851-A-G is described in ClinVar as Likely_benign. ClinVar VariationId is 2468188.Status of the report is criteria_provided_single_submitter, 1 stars.
