CC -!- TISSUE SPECIFICITY: Expressed in the adrenal gland.
CC {ECO:0000269|PubMed:1373808}.
CC -!- MISCELLANEOUS: TNX genes are located in the class III HLA region within
CC a complex locus, named RCCX module, containing genes for RP1/STK19,
CC C4B, CYP21B/CYP21A2 and TNXB. Most chromosomes bear 2 modules, but
CC monomodular and trimodular haplotypes are common in most populations.
CC The bimodular haplotype results from the duplication of the RCCX
CC module, leading to a duplicate containing RP2/RP1 pseudogene, C4A,
CC CYP21A/CYP21A1P and TNXA. TNXA is a duplicated section of TNXB and
CC probably consists in a truncated pseudogene: it contains a 120 bp
CC deletion causing a frameshift and a premature stop codon that probably
CC render the gene non-functional. In some pathologies, an unequal
CC crossover between monomodular and bimodular RCCX results in a
CC chromosome with a TNXB-TNXA hybrid gene, arising from a fusion between
CC the TNXB gene of a monomodular RCCX and the TNXA gene of a bimodular
CC RCCX. The TNXB-TNXA hybrid may correspond to TNXB-Short gene and may
CC produce a functional protein.
CC -!- CAUTION: Could be the product of a pseudogene. TNXA is
CC transcriptionally active in adrenal cortex but no protein product has
CC been observed. {ECO:0000305}.
