Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2023The c.2264G>A (p.R755H) alteration is located in exon 14 (coding exon 14) of the CPXM2 gene. This alteration results from a G to A substitution at nucleotide position 2264, causing the arginine (R) at amino acid position 755 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
