Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2023The c.2326C>T (p.R776W) alteration is located in exon 6 (coding exon 5) of the CCDC80 gene. This alteration results from a C to T substitution at nucleotide position 2326, causing the arginine (R) at amino acid position 776 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
