Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 12, 2023The c.23G>T (p.R8L) alteration is located in exon 1 (coding exon 1) of the WDR75 gene. This alteration results from a G to T substitution at nucleotide position 23, causing the arginine (R) at amino acid position 8 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
