Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 23, 2023The c.2300G>A (p.R767Q) alteration is located in exon 22 (coding exon 21) of the CC2D1B gene. This alteration results from a G to A substitution at nucleotide position 2300, causing the arginine (R) at amino acid position 767 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
