Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 24, 2024The c.864G>C (p.K288N) alteration is located in exon 5 (coding exon 3) of the CCDC157 gene. This alteration results from a G to C substitution at nucleotide position 864, causing the lysine (K) at amino acid position 288 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
