Genes affected

DNM1L (HGNC:2973): (dynamin 1 like) This gene encodes a member of the dynamin superfamily of GTPases. The encoded protein mediates mitochondrial and peroxisomal division, and is involved in developmentally regulated apoptosis and programmed necrosis. Dysfunction of this gene is implicated in several neurological disorders, including Alzheimer's disease. Mutations in this gene are associated with the autosomal dominant disorder, encephalopathy, lethal, due to defective mitochondrial and peroxisomal fission (EMPF). Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jun 2013]

DNM1L (HGNC:):

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP2: Missense variant in gene, where missense usually causes diseases (based on misZ statistic), DNM1L. . Gene score misZ 3.8282 (greater than the threshold 3.09). Trascript score misZ 5.3198 (greater than threshold 3.09). GenCC has associacion of gene with encephalopathy, lethal, due to defective mitochondrial peroxisomal fission 1, encephalopathy due to mitochondrial and peroxisomal fission defect, optic atrophy 5, Leigh syndrome, autosomal dominant optic atrophy, classic form.
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.894
• PP5: Variant 12-32679368-A-C is Pathogenic according to our data. Variant chr12-32679368-A-C is described in ClinVar as [Pathogenic]. Clinvar id is 446169.Status of the report is no_assertion_criteria_provided, 0 stars.
