Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2022The c.322G>T (p.V108L) alteration is located in exon 3 (coding exon 3) of the CCDC117 gene. This alteration results from a G to T substitution at nucleotide position 322, causing the valine (V) at amino acid position 108 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
