Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 03, 2024The c.1630G>A (p.D544N) alteration is located in exon 11 (coding exon 11) of the CPXM2 gene. This alteration results from a G to A substitution at nucleotide position 1630, causing the aspartic acid (D) at amino acid position 544 to be replaced by an asparagine (N). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
