Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 29, 2022The c.789A>T (p.Q263H) alteration is located in exon 5 (coding exon 4) of the ZNF449 gene. This alteration results from a A to T substitution at nucleotide position 789, causing the glutamine (Q) at amino acid position 263 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
