Genes affected

FBLIM1 (HGNC:24686): (filamin binding LIM protein 1) This gene encodes a protein with an N-terminal filamin-binding domain, a central proline-rich domain, and, multiple C-terminal LIM domains. This protein localizes at cell junctions and may link cell adhesion structures to the actin cytoskeleton. This protein may be involved in the assembly and stabilization of actin-filaments and likely plays a role in modulating cell adhesion, cell morphology and cell motility. This protein also localizes to the nucleus and may affect cardiomyocyte differentiation after binding with the CSX/NKX2-5 transcription factor. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2008]

Variant summary: FBLIM1 c.113G>A (p.Arg38Gln) results in a conservative amino acid change in the encoded protein sequence. Five of five in-silico tools predict a benign effect of the variant on protein function. The variant allele was found at a frequency of 0.0039 in 249050 control chromosomes in the gnomAD database, including 6 homozygotes. In addition, a study by Kars et al (2021) investigated the genetic structure of Turkey from 3,362 unrelated subjects and detected the variant in 18 homozygous individuals. c.113G>A has been reported in the literature in individuals affected with Chronic Osteomyelitis and developmental delay or intellectual disability (Cox_2017, dAdamo_2020, Hiraide_2021). These reports do not provide unequivocal conclusions about association of the variant with FBLIM1-Related Disorders. To our knowledge, no experimental evidence demonstrating an impact on protein function has been reported. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar after 2014. Based on the evidence outlined above, the variant was classified as uncertain significance. -
