Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.1850G>T (p.R617I) alteration is located in exon 12 (coding exon 12) of the WDR78 gene. This alteration results from a G to T substitution at nucleotide position 1850, causing the arginine (R) at amino acid position 617 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
