Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 22, 2024The c.1728T>G (p.H576Q) alteration is located in exon 16 (coding exon 16) of the RNGTT gene. This alteration results from a T to G substitution at nucleotide position 1728, causing the histidine (H) at amino acid position 576 to be replaced by a glutamine (Q). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
