Genes affected

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

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]

TRPA1 Gene-Disease associations (from GenCC):

• familial episodic pain syndrome with predominantly upper body involvement

  Inheritance: Unknown, AD Classification: SUPPORTIVE, LIMITED Submitted by: Labcorp Genetics (formerly Invitae), Orphanet, Ambry Genetics
• hereditary peripheral neuropathy

  Inheritance: AD Classification: LIMITED Submitted by: Ambry Genetics

ACMG classification

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

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.86).
• BP6: Variant 8-72053738-G-A is Benign according to our data. Variant chr8-72053738-G-A is described in ClinVar as Benign. ClinVar VariationId is 1342281.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
• BA1: GnomAd4 highest subpopulation (EAS) allele frequency at 95% confidence interval = 0.531 is higher than 0.05.
