Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 28, 2024The c.1166G>A (p.S389N) alteration is located in exon 9 (coding exon 9) of the CDC20B gene. This alteration results from a G to A substitution at nucleotide position 1166, causing the serine (S) at amino acid position 389 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
