Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 20, 2024The c.2017A>G (p.I673V) alteration is located in exon 3 (coding exon 2) of the CCDC80 gene. This alteration results from a A to G substitution at nucleotide position 2017, causing the isoleucine (I) at amino acid position 673 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
