Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 13, 2023The c.221G>A (p.R74Q) alteration is located in exon 3 (coding exon 3) of the ZDHHC17 gene. This alteration results from a G to A substitution at nucleotide position 221, causing the arginine (R) at amino acid position 74 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
