Review Status:criteria provided, single submitter

Collection Method:clinical testing

The c.824G>C (p.R275T) alteration is located in exon 10 (coding exon 9) of the PBLD gene. This alteration results from a G to C substitution at nucleotide position 824, causing the arginine (R) at amino acid position 275 to be replaced by a threonine (T). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
