The c.811C>T (p.P271S) alteration is located in exon 11 (coding exon 11) of the TBC1D19 gene. This alteration results from a C to T substitution at nucleotide position 811, causing the proline (P) at amino acid position 271 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
