Genes affected
WDR44 (HGNC:30512): (WD repeat domain 44) This gene encodes a protein that interacts with the small GTPase rab11. A similar protein in rat binds the GTP-containing active form of rab11. This protein may play a role in endosome recycling. Alternate splicing results in multiple transcript variants.[provided by RefSeq, May 2010]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 25, 2024The c.197G>T (p.S66I) alteration is located in exon 4 (coding exon 4) of the WDR44 gene. This alteration results from a G to T substitution at nucleotide position 197, causing the serine (S) at amino acid position 66 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
