Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 06, 2022The c.520C>T (p.R174W) alteration is located in exon 6 (coding exon 6) of the WDR75 gene. This alteration results from a C to T substitution at nucleotide position 520, causing the arginine (R) at amino acid position 174 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
