Review Status: criteria provided, single submitter

Collection Method: clinical testing

The c.215C>T (p.P72L) alteration is located in exon 4 (coding exon 3) of the TCTEX1D1 gene. This alteration results from a C to T substitution at nucleotide position 215, causing the proline (P) at amino acid position 72 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
