Family with sequence similarity 90 member A19 (FAM90A19)

Family with sequence similarity 90 member A19 (FAM90A19) is a primate-specific pseudogene belonging to the FAM90A gene family, which has arisen from multiple gene duplications and rearrangements in the primate lineage[1]. It is listed as a putative protein-coding gene, but its annotation as a pseudogene dominates, as no validated protein function or disease relevance has been established. \nMembers of the FAM90A family—including FAM90A19—are poorly characterized at the protein and functional level; there may be occasional RNA or peptide expression, but the significance remains speculative and mainly evolutionary[2][4][7]. \nPseudogenes like FAM90A19 might play a regulatory role by modulating gene expression via production of small interfering RNAs (siRNAs), but there is no direct evidence for such activity in FAM90A19 itself[8]. \nNo clinical or therapeutic applications, safety concerns, or biomarker utilities have been described for this gene. FAM90A19 illustrates the complexity and poor annotation of many pseudogenes in the human genome.\n\nIf additional, well-curated information on protein expression, functional experiments, or clinical relevance emerges, reclassification or update may be warranted, but as of now, FAM90A19 remains primarily a pseudogene with ambiguous protein-coding potential and no established biological role[1][4][7][9].
