Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 20, 2023The c.123C>A (p.S41R) alteration is located in exon 2 (coding exon 1) of the WDR54 gene. This alteration results from a C to A substitution at nucleotide position 123, causing the serine (S) at amino acid position 41 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
