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]

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

Multiple lines of computational evidence support a deleterious effect 8: AlphaMissense, BayesDel_addAF, BayesDel_noAF, M_CAP, phyloP100way_vertebrate, PrimateAI, PROVEAN, REVEL [when max_spliceai, FATHMM_MKL, MetaRNN, MutationTaster was below the threshold]

BP4

Computational evidence support a benign effect (MetaRNN=0.13416994).

BP6

Variant X-154348971-G-A is Benign according to our data. Variant chrX-154348971-G-A is described in ClinVar as [Benign]. Clinvar id is 413396.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1
