Genes affected

FKBP7 (HGNC:3723): (FKBP prolyl isomerase 7) The protein encoded by this gene belongs to the FKBP-type peptidyl-prolyl cis/trans isomerase (PPIase) family. Members of this family exhibit PPIase activity and function as molecular chaperones. A similar protein in mouse is located in the endoplasmic reticulum and binds calcium.

The c.535G>C (p.E179Q) alteration is located in exon 4 (coding exon 4) of the FKBP7 gene. This alteration results from a G to C substitution at nucleotide position 535, causing the glutamic acid (E) at amino acid position 179 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
