Fish odor syndrome (trimethylaminuria) supporting the possible FMO3 down expression in childhood: a case report

subtle 'heterozygous combi' 'FMO3 Malodor' case test : Messina TMAU test lab as with her parents and 1 of 2 bros, she carried 3 polymorphisms: E158K (rs 2266782) in exon 4, (IVS5+10G>C) (rs 2066534) and (IVS4-22G>A) (rs 1920149) in intronic regio

FMO3 > rs1920149 best is GG 45-65% carry A ? (23&me ppl can check) a clinic lab flagged it. its non-coding on intron. not part of fmo3 protein code. if bad must be a very small flaw. fmo3-malodor zone by many flaws ? only 1 case in pubmed https
