Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 17, 2023The c.1912A>G (p.T638A) alteration is located in exon 13 (coding exon 13) of the WDR78 gene. This alteration results from a A to G substitution at nucleotide position 1912, causing the threonine (T) at amino acid position 638 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
