Description

The c.551C>T (p.T184I) alteration is located in exon 4 (coding exon 4) of the NAPRT gene. This alteration results from a C to T substitution at nucleotide position 551, causing the threonine (T) at amino acid position 184 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear.
