Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.100G>A (p.V34M) alteration is located in exon 1 (coding exon 1) of the ZDHHC20 gene. This alteration results from a G to A substitution at nucleotide position 100, causing the valine (V) at amino acid position 34 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
