Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 04, 2022The c.1270G>A (p.E424K) alteration is located in exon 7 (coding exon 6) of the TBRG4 gene. This alteration results from a G to A substitution at nucleotide position 1270, causing the glutamic acid (E) at amino acid position 424 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
