Abstract excerpt
OBJECTIVE: Ectrodactyly-ectodermal dysplasia-clefting (EEC) syndrome is a rare autosomal dominant disorder caused by TP63 variants. De novo mutations challenge preimplantation genetic testing for monogenic disorders (PGT-M) when informative relatives are unavailable. This report describes a proband-independent PGT-M workflow for a de novo TP63 variant. CASE REPORT: Whole-exome sequencing identified a heterozygous...
