Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 23, 2023The c.277A>T (p.M93L) alteration is located in exon 4 (coding exon 4) of the ZNF20 gene. This alteration results from a A to T substitution at nucleotide position 277, causing the methionine (M) at amino acid position 93 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
