Abstract: The most frequently observed variations were T350G (100%) in E6, T789C (87.5%) in E7, A6695C (54.5%) in L1, and G7521A (91.1%) in the LCR.
Human papillomavirus typing of invasive cervical cancers in Italy.
Abstract: Of the 32 HPV 16 positive cases, sequencing of the E6 gene could be performed in 25; the prototype isolate was identified in 7, and the variant T350G in 18; in 4 cases one or more additional mutations were present.
Result: Interestingly, the A257G mutation has been firstly described very recently, and occurred in combination with the T350G variant, as in our case.
Result: Of the naturally occurring HPV 16 viral variants, the T350G (L83V) is the most commonly found among invasive cancers, and has been linked to an increased risk for cervical disease progression.

Detection and expression of human papillomavirus oncogenes in non-small cell lung cancer.
Abstract: Sequence analysis of the E6-E7 segments revealed three different HPV16 E6-E7 genotypes: the HPV16 prototype (6 of 21 cases), the E6 variant T350G (8 of 21 cases), and the E6-E7 variant A131G/C712A (7 of 21 cases).
Abstract: The E6 variants T350G and A131G have been associated with increased oncogenic potential in cervical cancer patients depending on host genetic factors.
[Causal association between human papilloma virus infection and head and neck and esophageal squamous cell carcinoma].
Abstract: Isolates were also analysed for the HPV 16 350T-G variant.
Abstract: No relationship was found between the E6 350T-G variant, or the E2 hinge region 3410C-T variant, and lesion grade.

Abstract: An initial sequence analysis of HPV-16 long control, E6 and E7 regions of 53 well-defined cervical samples containing HPV-16 revealed that a T to G transition at nucleotide position 350 within the E6 open reading frame was the most common variation, the frequency of which seemed to decrease with increasing severity of the lesion.
Rapid test for identification of a human papillomavirus 16 E6 L83V variant.
Abstract: This HPV 16 variant possesses a common mutation (T to G) in nucleotide 350 (codon 83) of the E6 gene, resulting in an amino acid shift, L83V, in the E6 protein.

Abstract: The most common variation detected was a T to G transition at base pair 350, resulting in an amino acid change from a leucine to a valine.
