Genes affected
FBXO42 (HGNC:29249): (F-box protein 42) Members of the F-box protein family, such as FBXO42, are characterized by an approximately 40-amino acid F-box motif. SCF complexes, formed by SKP1 (SKP1A; MIM 601434), cullin (see CUL1; MIM 603134), and F-box proteins, act as protein-ubiquitin ligases. F-box proteins interact with SKP1 through the F box, and they interact with ubiquitination targets through other protein interaction domains (Jin et al., 2004 [PubMed 15520277]).[supplied by OMIM, Dec 2010]

The c.1433T>C (p.I478T) alteration is located in exon 10 (coding exon 9) of the FBXO42 gene. This alteration results from a T to C substitution at nucleotide position 1433, causing the isoleucine (I) at amino acid position 478 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
