Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 31, 2024The c.1994G>T (p.G665V) alteration is located in exon 13 (coding exon 13) of the CPXM2 gene. This alteration results from a G to T substitution at nucleotide position 1994, causing the glycine (G) at amino acid position 665 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
