Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 08, 2024The c.136A>T (p.N46Y) alteration is located in exon 1 (coding exon 1) of the WDR43 gene. This alteration results from a A to T substitution at nucleotide position 136, causing the asparagine (N) at amino acid position 46 to be replaced by a tyrosine (Y). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
