Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 22, 2022The c.166A>G (p.K56E) alteration is located in exon 2 (coding exon 2) of the CCDC137 gene. This alteration results from a A to G substitution at nucleotide position 166, causing the lysine (K) at amino acid position 56 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
