Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 30, 2021The c.571A>G (p.T191A) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a A to G substitution at nucleotide position 571, causing the threonine (T) at amino acid position 191 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
