Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2022The c.824G>T (p.W275L) alteration is located in exon 9 (coding exon 9) of the WDR75 gene. This alteration results from a G to T substitution at nucleotide position 824, causing the tryptophan (W) at amino acid position 275 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
