Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 10, 2022The c.509C>T (p.P170L) alteration is located in exon 3 (coding exon 2) of the ZNF449 gene. This alteration results from a C to T substitution at nucleotide position 509, causing the proline (P) at amino acid position 170 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
