Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 26, 2022The c.667A>G (p.K223E) alteration is located in exon 3 (coding exon 3) of the CCDC3 gene. This alteration results from a A to G substitution at nucleotide position 667, causing the lysine (K) at amino acid position 223 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
