Illumina Clinical Services Laboratory,Illumina RCV001249696 SCV001423718 uncertain significance Cowden syndrome 1 2019-09-04 criteria provided, single submitter clinical testing The PTEN c.457G>C (p.Asp153His) variant is a missense variant. A literature search was performed for the gene, cDNA change, and amino acid change. No relevant publications were found based on this search. A different variant at the same position, c.457G>A (p.Asp153Asn), was reported in multiple individuals with breast cancer (Baig et al. 2011). The p.Asp153His variant is not found in the 1000 Genomes Project, the Exome Sequencing Project, Exome Aggregation Consortium, or the Genome Aggregation Database in a region of good sequencing coverage so the variant is presumed to be rare. This variant lies in exon 5, where a large proportion of disease-associated variants occur (Eng 2016). Based on the limited evidence, the p.Asp153His variant is classified as a variant of unknown significance for PTEN hamartoma tumor syndrome.
