Variant summary

Our verdict is Pathogenic. Variant got 10 ACMG points: 10P and 0B. PM1PM2PM5PP2PP3_ModeratePP5

The ENST00000369850.10(FLNA):​c.622G>C​(p.Gly208Arg) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a pathogenic outcome for this variant. 2/3 splice prediction tools predicting alterations to normal splicing. Variant has been reported in ClinVar as Pathogenic (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. G208C) has been classified as Likely pathogenic.

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 made for transcript

Verdict is Pathogenic. Variant got 10 ACMG points.

PM1
In a hotspot region, there are 4 aminoacids with missense pathogenic changes in the window of +-8 aminoacids around while only 0 benign, 3 uncertain in ENST00000369850.10
PM2
Very rare variant in population databases, with high coverage;
PM5
Other missense variant is known to change same aminoacid residue: Variant chrX-154367842-C-A is described in ClinVar as [Likely_pathogenic]. Clinvar id is 3376601.Status of the report is criteria_provided_single_submitter, 1 stars.
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), FLNA. . Gene score misZ 3.7802 (greater than the threshold 3.09). GenCC has associacion of gene with X-linked Ehlers-Danlos syndrome, terminal osseous dysplasia-pigmentary defects syndrome, FG syndrome 2, frontometaphyseal dysplasia, heterotopia, periventricular, X-linked dominant, Melnick-Needles syndrome, otopalatodigital syndrome type 2, periventricular nodular heterotopia, otopalatodigital syndrome type 1, intestinal pseudoobstruction, neuronal, chronic idiopathic, X-linked, familial thoracic aortic aneurysm and aortic dissection, congenital short bowel syndrome, frontometaphyseal dysplasia 1, cardiac valvular dysplasia, X-linked.
PP3
MetaRNN computational evidence supports a deleterious effect, 0.933
PP5
Variant X-154367842-C-G is Pathogenic according to our data. Variant chrX-154367842-C-G is described in ClinVar as [Pathogenic]. Clinvar id is 209069.Status of the report is no_assertion_criteria_provided, 0 stars.
