Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsAug 02, 2021The c.1370G>A (p.R457Q) alteration is located in exon 14 (coding exon 12) of the TERB1 gene. This alteration results from a G to A substitution at nucleotide position 1370, causing the arginine (R) at amino acid position 457 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
