Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJan 22, 2024The c.1645A>G (p.T549A) alteration is located in exon 9 (coding exon 8) of the TBRG4 gene. This alteration results from a A to G substitution at nucleotide position 1645, causing the threonine (T) at amino acid position 549 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
