Genes affected

OMA1 (HGNC:29661): (OMA1 zinc metallopeptidase) Enables metalloendopeptidase activity. Involved in several processes, including HRI-mediated signaling; proteolysis; and regulation of mitochondrion organization. Located in mitochondrial inner membrane. [provided by Alliance of Genome Resources, Apr 2022]

DAB1 (HGNC:2661): (DAB adaptor protein 1) The laminar organization of multiple neuronal types in the cerebral cortex is required for normal cognitive function. In mice, the disabled-1 gene plays a central role in brain development, directing the migration of cortical neurons past previously formed neurons to reach their proper layer. This gene is similar to disabled-1, and the protein encoded by this gene is thought to be a signal transducer that interacts with protein kinase pathways to regulate neuronal positioning in the developing brain.

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.0035673082).
• BP6: Variant 1-58539090-G-A is Benign according to our data. Variant chr1-58539090-G-A is described in ClinVar as [Benign]. Clinvar id is 767673.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BS1: Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00758 (1154/152260) while in subpopulation AFR AF= 0.0196 (815/41572). AF 95% confidence interval is 0.0185. There are 7 homozygotes in gnomad4. There are 555 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 7 AR gene
