Variant summary

Our verdict is Benign. The variant received -13 ACMG points: 0P and 13B. BP4_StrongBP6BS1BS2

The ENST00000369850.10(FLNA):c.5251C>T(p.Pro1751Ser) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000767 in 1,206,829 control chromosomes in the GnomAD database, including 1 homozygotes. There are 332 hemizygotes in GnomAD. In-silico tool predicts a benign outcome for this variant. 16/21 in silico tools predict 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. P1751L) has been classified as Uncertain significance.

Genes affected

FLNA (HGNC:3754): (filamin A) The protein encoded by this gene is an actin-binding protein that crosslinks actin filaments and links actin filaments to membrane glycoproteins. The encoded protein is involved in remodeling the cytoskeleton to effect changes in cell shape and migration. This protein interacts with integrins, transmembrane receptor complexes, and second messengers. Defects in this gene are a cause of several syndromes, including periventricular nodular heterotopias (PVNH1, PVNH4), otopalatodigital syndromes (OPD1, OPD2), frontometaphyseal dysplasia (FMD), Melnick-Needles syndrome (MNS), and X-linked congenital idiopathic intestinal pseudoobstruction (CIIPX). Two transcript variants encoding different isoforms have been found for this gene.[provided by RefSeq, Mar 2009]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.0062868297).

BP6

Variant X-154354678-G-A is Benign according to our data. Variant chrX-154354678-G-A is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 213451.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.000724 (82/113273) while in subpopulation NFE AF = 0.00105 (56/53280). AF 95% confidence interval is 0.000831. There are 0 homozygotes in GnomAd4. There are 22 alleles in the male GnomAd4 subpopulation. Median coverage is 26. This position passed quality control check.

BS2

High Hemizygotes in GnomAd4 at 22 XL,AD,AR gene
