Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 12, 2023The c.1675G>A (p.V559I) alteration is located in exon 18 (coding exon 18) of the ACAP3 gene. This alteration results from a G to A substitution at nucleotide position 1675, causing the valine (V) at amino acid position 559 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
