Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 16, 2021The c.770G>T (p.C257F) alteration is located in exon 5 (coding exon 4) of the ZNF33A gene. This alteration results from a G to T substitution at nucleotide position 770, causing the cysteine (C) at amino acid position 257 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
