Genes affected

FHL2 (HGNC:3703): (four and a half LIM domains 2) This gene encodes a member of the four-and-a-half-LIM-only protein family. Family members contain two highly conserved, tandemly arranged, zinc finger domains with four highly conserved cysteines binding a zinc atom in each zinc finger. This protein is thought to have a role in the assembly of extracellular membranes. Also, this gene is down-regulated during transformation of normal myoblasts to rhabdomyosarcoma cells and the encoded protein may function as a link between presenilin-2 and an intracellular signaling pathway. Multiple alternatively spliced variants encoding different isoforms have been identified. [provided by RefSeq, Jan 2016]

The p.Leu21Gln variant in FHL2 not been previously reported in individuals with cardiomyopathy, but has been identified in 2/66712 European chromosomes by the E xome Aggregation Consortium (ExAC, http://exac.broadinstitute.org; dbSNP rs75580 5016). Computational prediction tools and conservation analysis do not provide s trong support for or against an impact to the protein. In summary, the clinical significance of the p.Leu21Gln variant is uncertain. -

In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be disruptive. ClinVar contains an entry for this variant (Variation ID: 504936). This variant has not been reported in the literature in individuals affected with FHL2-related conditions. This variant is present in population databases (rs755805016, gnomAD 0.006%). This sequence change replaces leucine, which is neutral and non-polar, with glutamine, which is neutral and polar, at codon 21 of the FHL2 protein (p.Leu21Gln). -
