Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.1771A>G (p.K591E) alteration is located in exon 15 (coding exon 15) of the WDR46 gene. This alteration results from a A to G substitution at nucleotide position 1771, causing the lysine (K) at amino acid position 591 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
