Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 28, 2022The c.196A>T (p.S66C) alteration is located in exon 4 (coding exon 4) of the NT5C3B gene. This alteration results from a A to T substitution at nucleotide position 196, causing the serine (S) at amino acid position 66 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
