Genes affected
CFAP251 (HGNC:28506): (cilia and flagella associated protein 251) This protein encoded by this gene belongs to the WD repeat-containing family of proteins, which function in the formation of protein-protein complexes in a variety of biological pathways. This family member appears to function in the determination of mean platelet volume (MPV), and polymorphisms in this gene have been associated with variance in MPV. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Sep 2011]

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.178G>A (p.E60K) alteration is located in exon 2 (coding exon 1) of the WDR66 gene. This alteration results from a G to A substitution at nucleotide position 178, causing the glutamic acid (E) at amino acid position 60 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
