Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 15, 2024The c.198C>A (p.N66K) alteration is located in exon 2 (coding exon 2) of the WDR75 gene. This alteration results from a C to A substitution at nucleotide position 198, causing the asparagine (N) at amino acid position 66 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
