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]

FLNC-AS1 (HGNC:53474): (FLNC antisense RNA 1)

ACMG classification

Verdict is Benign. Variant got -20 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.85).
• BP6: Variant 7-128852763-G-A is Benign according to our data. Variant chr7-128852763-G-A is described in ClinVar as [Benign]. Clinvar id is 258151.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars. Variant chr7-128852763-G-A is described in Lovd as [Benign]. Variant chr7-128852763-G-A is described in Lovd as [Likely_benign].
• BS1: Variant frequency is greater than expected in population nfe. gnomad4 allele frequency = 0.00705 (1074/152248) while in subpopulation NFE AF= 0.0112 (759/67986). AF 95% confidence interval is 0.0105. There are 7 homozygotes in gnomad4. There are 482 alleles in male gnomad4 subpopulation. This position pass quality control queck.
• BS2: High AC in GnomAd at 1075 AD gene.
