Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.869T>A (p.V290D) alteration is located in exon 3 (coding exon 2) of the ZDHHC23 gene. This alteration results from a T to A substitution at nucleotide position 869, causing the valine (V) at amino acid position 290 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
