Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 21, 2022The c.523C>T (p.R175C) alteration is located in exon 6 (coding exon 6) of the RNGTT gene. This alteration results from a C to T substitution at nucleotide position 523, causing the arginine (R) at amino acid position 175 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
