Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 18, 2023The c.391G>A (p.A131T) alteration is located in exon 2 (coding exon 1) of the CPQ gene. This alteration results from a G to A substitution at nucleotide position 391, causing the alanine (A) at amino acid position 131 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
