Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 03, 2023The c.1333A>G (p.T445A) alteration is located in exon 12 (coding exon 12) of the RNGTT gene. This alteration results from a A to G substitution at nucleotide position 1333, causing the threonine (T) at amino acid position 445 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
