The c.332T>C (p.I111T) alteration is located in exon 4 (coding exon 4) of the UBAC2 gene. This alteration results from a T to C substitution at nucleotide position 332, causing the isoleucine (I) at amino acid position 111 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
