Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsApr 07, 2022The c.1237G>A (p.V413M) alteration is located in exon 5 (coding exon 5) of the CDR2 gene. This alteration results from a G to A substitution at nucleotide position 1237, causing the valine (V) at amino acid position 413 to be replaced by a methionine (M). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
