Significance: Uncertain significance

Review Status: criteria provided, single submitter

Collection Method: clinical testing

The p.Y616C variant (also known as c.1847A>G), located in coding exon 16 of the PRDM5 gene, results from an A to G substitution at nucleotide position 1847. The tyrosine at codon 616 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, the in silico prediction for this alteration is inconclusive. Based on the available evidence, the clinical significance of this variant remains unclear. -
