These are other antibodies to proteins in the nuclei.
Includes -
- anti-Sm
- anti-Ro (especially associated
with lupus skin disease, heartblock in neonates and Sjögrens
syndrome. It can 'leak' across the placenta and lead to slow heartbeat
in the developing foetus: this can require a 'blood change' as soon
as the baby is born.)
- anti-La (SLE, Sjögrens
syndrome)
- anti-RNP (if present
with antibodies to DNA, then diagnosis is SLE, if present alone,
then diagnosis is mixed connective tissue disease, MCTD)
- Anti-Scl70 (systemic
sclerosis)
- Anti-Jol (polymyositis)
- And others
