Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 09, 2023The c.543G>T (p.K181N) alteration is located in exon 4 (coding exon 4) of the WDR43 gene. This alteration results from a G to T substitution at nucleotide position 543, causing the lysine (K) at amino acid position 181 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
