Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.1970C>T (p.A657V) alteration is located in exon 21 (coding exon 21) of the ACAP3 gene. This alteration results from a C to T substitution at nucleotide position 1970, causing the alanine (A) at amino acid position 657 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
