Genes affected
TRPC6 (HGNC:12338): (transient receptor potential cation channel subfamily C member 6) The protein encoded by this gene forms a receptor-activated calcium channel in the cell membrane. The channel is activated by diacylglycerol and is thought to be under the control of a phosphatidylinositol second messenger system. Activation of this channel occurs independently of protein kinase C and is not triggered by low levels of intracellular calcium. Defects in this gene are a cause of focal segmental glomerulosclerosis 2 (FSGS2). [provided by RefSeq, Mar 2009]

ACMG classification

Classification was made for transcript

Our verdict: Uncertain_significance. The variant received 4 ACMG points.

PM5
Other missense variant is known to change same aminoacid residue: Variant chr11-101504325-C-T is described in ClinVar as Likely_pathogenic. ClinVar VariationId is 988133.Status of the report is criteria_provided_single_submitter, 1 stars.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.873
PP5
Variant 11-101504326-G-A is Pathogenic according to our data. Variant chr11-101504326-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 562374.
BS2
High AC in GnomAdExome4 at 5 AD gene. Variant has AC lower than other variant known as pathogenic in the gene, so the strength is limited to Supporting.
