Genes affected
FLNC (HGNC:3756): (filamin C) This gene encodes one of three related filamin genes, specifically gamma filamin. These filamin proteins crosslink actin filaments into orthogonal networks in cortical cytoplasm and participate in the anchoring of membrane proteins for the actin cytoskeleton. Three functional domains exist in filamin: an N-terminal filamentous actin-binding domain, a C-terminal self-association domain, and a membrane glycoprotein-binding domain. Mutations in this gene are a cause of cardiopathy. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, May 2022]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -15 ACMG points.

PP3
Splicing predictors support a deleterious effect. Scorers claiming Pathogenic: max_spliceai. No scorers claiming Uncertain. No scorers claiming Benign.
BP6
Variant 7-128845230-C-A is Benign according to our data. Variant chr7-128845230-C-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 472047.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.
BS1
Variant frequency is greater than expected in population sas. GnomAd4 allele frequency = 0.000322 (49/152328) while in subpopulation SAS AF = 0.00995 (48/4824). AF 95% confidence interval is 0.00771. There are 2 homozygotes in GnomAd4. There are 36 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.
BS2
High AC in GnomAd4 at 49 AD gene.
