Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 06, 2023The c.2687G>A (p.R896Q) 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 2687, causing the arginine (R) at amino acid position 896 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
