Genes affected
FHL3 (HGNC:3704): (four and a half LIM domains 3) The protein encoded by this gene is a member of a family of proteins containing a four-and-a-half LIM domain, which is a highly conserved double zinc finger motif. The encoded protein has been shown to interact with the cancer developmental regulators SMAD2, SMAD3, and SMAD4, the skeletal muscle myogenesis protein MyoD, and the high-affinity IgE beta chain regulator MZF-1. This protein may be involved in tumor suppression, repression of MyoD expression, and repression of IgE receptor expression. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2011]

The c.770C>G (p.S257C) alteration is located in exon 6 (coding exon 5) of the FHL3 gene. This alteration results from a C to G substitution at nucleotide position 770, causing the serine (S) at amino acid position 257 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
