Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 07, 2023The c.1778C>T (p.A593V) alteration is located in exon 15 (coding exon 15) of the WDR46 gene. This alteration results from a C to T substitution at nucleotide position 1778, causing the alanine (A) at amino acid position 593 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
