The c.2912T>C (p.V971A) alteration is located in exon 18 (coding exon 17) of the CLUH gene. This alteration results from a T to C substitution at nucleotide position 2912, causing the valine (V) at amino acid position 971 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
