Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsMar 07, 2024The c.478G>A (p.A160T) alteration is located in exon 2 (coding exon 1) of the CGN gene. This alteration results from a G to A substitution at nucleotide position 478, causing the alanine (A) at amino acid position 160 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
