Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.2375A>G (p.N792S) alteration is located in exon 18 (coding exon 16) of the GTF3C2 gene. This alteration results from a A to G substitution at nucleotide position 2375, causing the asparagine (N) at amino acid position 792 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
