Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 06, 2023The c.47C>T (p.A16V) alteration is located in exon 1 (coding exon 1) of the CCDC12 gene. This alteration results from a C to T substitution at nucleotide position 47, causing the alanine (A) at amino acid position 16 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
