Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 14, 2023The c.2734G>A (p.V912I) alteration is located in exon 17 (coding exon 17) of the CCDC191 gene. This alteration results from a G to A substitution at nucleotide position 2734, causing the valine (V) at amino acid position 912 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
