Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 13, 2024The c.772C>T (p.R258C) alteration is located in exon 2 (coding exon 1) of the ZNF646 gene. This alteration results from a C to T substitution at nucleotide position 772, causing the arginine (R) at amino acid position 258 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
