Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsJun 17, 2024The c.794A>T (p.Y265F) alteration is located in exon 6 (coding exon 6) of the NT5C1A gene. This alteration results from a A to T substitution at nucleotide position 794, causing the tyrosine (Y) at amino acid position 265 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
