Genes affected
IFT52 (HGNC:15901): (intraflagellar transport 52) This gene encodes a conserved proline-rich protein that is a component of the intraflagellar transport-B (IFT-B) core complex. The encoded protein is essential for the integrity of the IFT-B core complex, and for biosynthesis and maintenance of cilia. Mutations in this gene are associated with ciliopathy that affects the skeleton. [provided by RefSeq, Oct 2016]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 02, 2023The c.188A>G (p.E63G) alteration is located in exon 3 (coding exon 2) of the IFT52 gene. This alteration results from a A to G substitution at nucleotide position 188, causing the glutamic acid (E) at amino acid position 63 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
