Collection Method: clinical testing

The c.729G>T (p.L243F) alteration is located in exon 4 (coding exon 4) of the YRDC gene. This alteration results from a G to T substitution at nucleotide position 729, causing the leucine (L) at amino acid position 243 to be replaced by a phenylalanine (F). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
