Genes affected

MTX1 (HGNC:7504): (metaxin 1) Predicted to be involved in mitochondrion organization. Part of MIB complex and SAM complex. [provided by Alliance of Genome Resources, Apr 2022]

THBS3 (HGNC:11787): (thrombospondin 3) The protein encoded by this gene belongs to the thrombospondin family. Thrombospondin family members are adhesive glycoproteins that mediate cell-to-cell and cell-to-matrix interactions. This protein forms a pentameric molecule linked by a single disulfide bond. This gene shares a common promoter with metaxin 1. Alternate splicing results in coding and non-coding transcript variants. [provided by RefSeq, Nov 2011]

THBS3 Gene-Disease associations (from GenCC):

• Tourette syndrome

  Inheritance: Unknown Classification: NO_KNOWN Submitted by: Labcorp Genetics (formerly Invitae)

ACMG classification

Our verdict: Benign. The variant received -14 ACMG points.

• BP4: Computational evidence support a benign effect (MetaRNN=0.002467364).
• BP6: Variant 1-155208991-T-A is Benign according to our data. Variant chr1-155208991-T-A is described in ClinVar as Benign. ClinVar VariationId is 767706.Status of the report is criteria_provided_single_submitter, 1 stars.
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.398 is higher than 0.05.
