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.554G>A (p.R185H) alteration is located in exon 4 (coding exon 4) of the FKBP7 gene. This alteration results from a G to A substitution at nucleotide position 554, causing the arginine (R) at amino acid position 185 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
