Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 19, 2022The c.2543G>A (p.S848N) alteration is located in exon 3 (coding exon 1) of the ZBTB21 gene. This alteration results from a G to A substitution at nucleotide position 2543, causing the serine (S) at amino acid position 848 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
