Genes affected

TRPA1 (HGNC:497): (transient receptor potential cation channel subfamily A member 1) The structure of the protein encoded by this gene is highly related to both the protein ankyrin and transmembrane proteins. The specific function of this protein has not yet been determined; however, studies indicate the function may involve a role in signal transduction and growth control. [provided by RefSeq, Jul 2008]

MSC-AS1 (HGNC:48724): (MSC antisense RNA 1)

ACMG classification

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

• BP4: Computational evidence support a benign effect (MetaRNN=7.347031E-7).
• BP6: Variant 8-72063566-T-G is Benign according to our data. Variant chr8-72063566-T-G is described in ClinVar as Benign. ClinVar VariationId is 1342284.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.955 is higher than 0.05.
