Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2BP4_Moderate

The ENST00000391842.6(PTOV1):c.17G>A(p.Arg6His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0000434 in 138,278 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. R6C) has been classified as Uncertain significance.

Genes affected

PTOV1 (HGNC:9632): (PTOV1 extended AT-hook containing adaptor protein) This gene encodes a protein that was found to be overexpressed in prostate adenocarcinomas. The encoded protein was found to interact with the lipid raft protein flotillin-1 and shuttle it from the cytoplasm to the nucleus in a cell cycle dependent manner. Alternative splicing of this gene results in multiple transcript variants. [provided by RefSeq, Feb 2015]

The c.17G>A (p.R6H) alteration is located in exon 1 (coding exon 1) of the PTOV1 gene. This alteration results from a G to A substitution at nucleotide position 17, causing the arginine (R) at amino acid position 6 to be replaced by a histidine (H). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
