Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsOct 06, 2024The c.827G>A (p.R276H) alteration is located in exon 6 (coding exon 6) of the NT5C1A gene. This alteration results from a G to A substitution at nucleotide position 827, causing the arginine (R) at amino acid position 276 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
