Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 12, 2021The c.28C>G (p.R10G) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a C to G substitution at nucleotide position 28, causing the arginine (R) at amino acid position 10 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
