1Abstract: When samples with ""a"" variants were evaluated by two different commercial HBsAg tests, only the isolate with Ser143Leu variation had a decreased reactivity in the assay using monoclonal antibodies for capture and detection."

Abstract: Analysis of primary nucleotide sequence revealed serologically meaningful mutations in S-gene of HBV in all 9 isolates: 3 of them contained substitution mutation G145R, 5--S143L, and one--T143M.
Abstract: Prevalence of HBsAg mutations in HBV carriers with high level of HBsAg was assessed for the first time: prevalence of G145R, S143L/T143M mutations, and all serologically atypical variants was 0.12%, 0.24%, and 0.76% respectively.
A new hepatitis B virus vaccine escape mutation in a renal transplant recipient.
1Abstract: The sequencing data showed that the HBV strain carried five amino acid substitutions in the major hydrophilic region of the S protein, one (sS143L) located at the ""a"" determinant."
Characterization of naturally occurring and Lamivudine-induced surface gene mutants of hepatitis B virus in patients with chronic hepatitis B in India.
Abstract: Following lamivudine therapy, 14 of 57 (24.5%) patients developed 16 types of S-gene mutations (sP120S, sA128V, sS143L, sW182St., sT189I, sV190A, sS193L, sI195M, sW196L, sW196St., sS207R,
