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]

ENSG00000238273 (HGNC:):

C2orf49 (HGNC:28772): (chromosome 2 open reading frame 49) Predicted to be involved in embryonic morphogenesis. Located in nucleus. Part of tRNA-splicing ligase complex. [provided by Alliance of Genome Resources, Apr 2022]
