Genes affected

FKBP1B (HGNC:3712): (FKBP prolyl isomerase 1B) The protein encoded by this gene is a member of the immunophilin protein family, which play a role in immunoregulation and basic cellular processes involving protein folding and trafficking. This encoded protein is a cis-trans prolyl isomerase that binds the immunosuppressants FK506 and rapamycin. It is highly similar to the FK506-binding protein 1A. Its physiological role is thought to be in excitation-contraction coupling in cardiac muscle. There are two alternatively spliced transcript variants of this gene encoding different isoforms.

The c.194C>G (p.A65G) alteration is located in exon 3 (coding exon 3) of the FKBP1B gene. This alteration results from a C to G substitution at nucleotide position 194, causing the alanine (A) at amino acid position 65 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
