Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2024The c.2216C>T (p.P739L) alteration is located in exon 15 (coding exon 15) of the WDR78 gene. This alteration results from a C to T substitution at nucleotide position 2216, causing the proline (P) at amino acid position 739 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
