Description

This variant is considered likely benign or benign based on one or more of the following criteria: it is a conservative change, it occurs at a poorly conserved position in the protein, it is predicted to be benign by multiple in silico algorithms, and/or has population frequency not consistent with disease.

Description

Variant summary: FLNA c.6023-10C>G alters a non-conserved nucleotide located at a position not widely known to affect splicing. Consensus agreement among computation tools predict no significant impact on normal splicing. However, these predictions have yet to be confirmed by functional studies. The variant allele was found at a frequency of 0.0037 in 181586 control chromosomes in the gnomAD database, including 4 homozygotes. The observed variant frequency is approximately 11771-fold of the estimated maximal expected allele frequency for a pathogenic variant in FLNA causing Periventricular Nodular Heterotopia phenotype (3.1e-07), strongly suggesting that the variant is benign. To our knowledge, no occurrence of c.6023-10C>G in individuals affected with Periventricular Nodular Heterotopia and no experimental evidence demonstrating its impact on protein function have been reported. ClinVar contains an entry for this variant (Variation ID: 211021). Based on the evidence outlined above, the variant was classified as benign.
