Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 22, 2023The c.376G>T (p.G126W) alteration is located in exon 1 (coding exon 1) of the CNNM3 gene. This alteration results from a G to T substitution at nucleotide position 376, causing the glycine (G) at amino acid position 126 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
