Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 14, 2023The c.204G>A (p.M68I) alteration is located in exon 2 (coding exon 1) of the ZNF446 gene. This alteration results from a G to A substitution at nucleotide position 204, causing the methionine (M) at amino acid position 68 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
