Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 19, 2022The c.67A>C (p.K23Q) alteration is located in exon 2 (coding exon 1) of the CCDC7 gene. This alteration results from a A to C substitution at nucleotide position 67, causing the lysine (K) at amino acid position 23 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
