Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJul 14, 2021The c.1369C>T (p.R457C) alteration is located in exon 14 (coding exon 14) of the GFPT2 gene. This alteration results from a C to T substitution at nucleotide position 1369, causing the arginine (R) at amino acid position 457 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
