Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 1P and 13B. PP2BP4_StrongBP6BS1BS2

The ENST00000325888.13(FLNC):​c.1535C>T​(p.Thr512Met) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000409 in 1,613,770 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. T512K) has been classified as Uncertain significance.

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 made for transcript

Verdict is Benign. Variant got -12 ACMG points.

PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), FLNC. . Gene score misZ 2.789 (greater than the threshold 3.09). Trascript score misZ 5.9457 (greater than threshold 3.09). GenCC has associacion of gene with dilated cardiomyopathy, heart conduction disease, familial isolated restrictive cardiomyopathy, hypertrophic cardiomyopathy 26, distal myopathy with posterior leg and anterior hand involvement, myofibrillar myopathy 5.
BP4
Computational evidence support a benign effect (MetaRNN=0.055946887).
BP6
Variant 7-128840146-C-T is Benign according to our data. Variant chr7-128840146-C-T is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 772701.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=2}.
BS1
Variant frequency is greater than expected in population amr. gnomad4_exome allele frequency = 0.0000417 (61/1461578) while in subpopulation AMR AF= 0.00107 (48/44720). AF 95% confidence interval is 0.000832. There are 0 homozygotes in gnomad4_exome. There are 21 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAd4 at 5 AD gene.
