Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 01, 2024The c.2230C>T (p.R744W) alteration is located in exon 14 (coding exon 14) of the CPXM2 gene. This alteration results from a C to T substitution at nucleotide position 2230, causing the arginine (R) at amino acid position 744 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
