Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 29, 2021The c.1801T>G (p.L601V) alteration is located in exon 14 (coding exon 12) of the GTF3C2 gene. This alteration results from a T to G substitution at nucleotide position 1801, causing the leucine (L) at amino acid position 601 to be replaced by a valine (V). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
