Genes affected

FBXO33 (HGNC:19833): (F-box protein 33) This locus represents an member of the F-box gene family. The encoded protein contains an F-box motif and a domain that might form a structure similar to a leucine-rich repeat found in placental RNAse inhibitor. This locus may be associated with copy number variation of UGT2B17 (GeneID 7367), which has been associated with susceptibility to osteoporosis.[provided by RefSeq, Sep 2010]

Collection Method: clinical testing

The c.1112G>T (p.R371L) alteration is located in exon 3 (coding exon 3) of the FBXO33 gene. This alteration results from a G to T substitution at nucleotide position 1112, causing the arginine (R) at amino acid position 371 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
