Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2023The c.667T>A (p.S223T) alteration is located in exon 4 (coding exon 4) of the ZNF493 gene. This alteration results from a T to A substitution at nucleotide position 667, causing the serine (S) at amino acid position 223 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
