Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 10, 2023The c.1139G>A (p.R380Q) alteration is located in exon 11 (coding exon 11) of the CCDC91 gene. This alteration results from a G to A substitution at nucleotide position 1139, causing the arginine (R) at amino acid position 380 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
