Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 10, 2022The c.675G>C (p.K225N) alteration is located in exon 4 (coding exon 4) of the CCDC27 gene. This alteration results from a G to C substitution at nucleotide position 675, causing the lysine (K) at amino acid position 225 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
