Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 16, 2023The c.997T>G (p.F333V) alteration is located in exon 4 (coding exon 3) of the ZDHHC23 gene. This alteration results from a T to G substitution at nucleotide position 997, causing the phenylalanine (F) at amino acid position 333 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
