Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 17, 2021The c.725A>G (p.N242S) alteration is located in exon 7 (coding exon 7) of the CNN1 gene. This alteration results from a A to G substitution at nucleotide position 725, causing the asparagine (N) at amino acid position 242 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
