Genes affected

AAAS (HGNC:13666): (aladin WD repeat nucleoporin) The protein encoded by this gene is a member of the WD-repeat family of regulatory proteins and may be involved in normal development of the peripheral and central nervous system. The encoded protein is part of the nuclear pore complex and is anchored there by NDC1. Defects in this gene are a cause of achalasia-addisonianism-alacrima syndrome (AAAS), also called triple-A syndrome or Allgrove syndrome. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Mar 2010]

MYG1 (HGNC:17590): (MYG1 exonuclease) Predicted to enable nuclease activity. Predicted to be involved in nucleic acid phosphodiester bond hydrolysis. Predicted to act upstream of or within locomotory exploration behavior. Located in mitochondrion and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

ENSG00000288663 (HGNC:):

ACMG classification

Our verdict: Benign. The variant received -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.9).
• BP6: Variant 12-53307320-T-C is Benign according to our data. Variant chr12-53307320-T-C is described in ClinVar as Benign. ClinVar VariationId is 1264842.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (NFE) allele frequency at 95% confidence interval = 0.979 is higher than 0.05.
