Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsFeb 12, 2024The c.70A>G (p.T24A) alteration is located in exon 2 (coding exon 1) of the CGN gene. This alteration results from a A to G substitution at nucleotide position 70, causing the threonine (T) at amino acid position 24 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
