Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 26, 2022The c.1223C>T (p.T408M) alteration is located in exon 4 (coding exon 3) of the ZBTB8B gene. This alteration results from a C to T substitution at nucleotide position 1223, causing the threonine (T) at amino acid position 408 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
