Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 14, 2023The c.2307G>C (p.Q769H) alteration is located in exon 23 (coding exon 23) of the ACAP3 gene. This alteration results from a G to C substitution at nucleotide position 2307, causing the glutamine (Q) at amino acid position 769 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
