Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 06, 2023The c.967C>T (p.R323C) alteration is located in exon 6 (coding exon 5) of the CPQ gene. This alteration results from a C to T substitution at nucleotide position 967, causing the arginine (R) at amino acid position 323 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
