Collection Method: clinical testing

The c.100C>T (p.P34S) alteration is located in exon 3 (coding exon 1) of the TCF24 gene. This alteration results from a C to T substitution at nucleotide position 100, causing the proline (P) at amino acid position 34 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
