Genes affected
NT5C1B (HGNC:17818): (5'-nucleotidase, cytosolic IB) Cytosolic 5-prime nucleotidases, such as NT5C1B, catalyze production of adenosine, which regulates diverse physiologic processes (Sala-Newby and Newby, 2001 [PubMed 11690631]).[supplied by OMIM, Mar 2008]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 30, 2022The c.1435C>T (p.L479F) alteration is located in exon 9 (coding exon 9) of the NT5C1B gene. This alteration results from a C to T substitution at nucleotide position 1435, causing the leucine (L) at amino acid position 479 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
