Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsNov 18, 2023The c.76G>A (p.E26K) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a G to A substitution at nucleotide position 76, causing the glutamic acid (E) at amino acid position 26 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
