Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2022The c.497G>A (p.R166H) alteration is located in exon 7 (coding exon 4) of the ZDHHC21 gene. This alteration results from a G to A substitution at nucleotide position 497, causing the arginine (R) at amino acid position 166 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
