Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.296T>G (p.I99S) alteration is located in exon 4 (coding exon 4) of the NUBP1 gene. This alteration results from a T to G substitution at nucleotide position 296, causing the isoleucine (I) at amino acid position 99 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
