Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMay 09, 2024The c.373C>G (p.Q125E) alteration is located in exon 4 (coding exon 3) of the CCDC18 gene. This alteration results from a C to G substitution at nucleotide position 373, causing the glutamine (Q) at amino acid position 125 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
