The c.1909T>C (p.C637R) alteration is located in exon 12 (coding exon 11) of the USHBP1 gene. This alteration results from a T to C substitution at nucleotide position 1909, causing the cysteine (C) at amino acid position 637 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
