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.477G>A (p.M159I) alteration is located in exon 3 (coding exon 3) of the FKBP7 gene. This alteration results from a G to A substitution at nucleotide position 477, causing the methionine (M) at amino acid position 159 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
