The c.88T>C (p.C30R) alteration is located in exon 3 (coding exon 2) of the TMEM71 gene. This alteration results from a T to C substitution at nucleotide position 88, causing the cysteine (C) at amino acid position 30 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
