Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2024The c.122A>G (p.D41G) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a A to G substitution at nucleotide position 122, causing the aspartic acid (D) at amino acid position 41 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
