Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024The c.505G>A (p.V169I) alteration is located in exon 3 (coding exon 2) of the ZDHHC23 gene. This alteration results from a G to A substitution at nucleotide position 505, causing the valine (V) at amino acid position 169 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
