The c.11C>G (p.P4R) alteration is located in exon 3 (coding exon 1) of the TCEAL7 gene. This alteration results from a C to G substitution at nucleotide position 11, causing the proline (P) at amino acid position 4 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
