Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 28, 2022The c.1825A>G (p.I609V) alteration is located in exon 12 (coding exon 12) of the CPXM2 gene. This alteration results from a A to G substitution at nucleotide position 1825, causing the isoleucine (I) at amino acid position 609 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
