medical condition
Tibial hemimelia-polysyndactyly-triphalangeal thumb syndrome is a rare genetic limb malformation syndrome which is characterized by thumb triphalangy, polysyndactyly of the hand and foot, and hypoplasia/aplasia of the tibia bone. Additional features include short stature, radio-ulnar synostosis, ectrodactyly and abnormalities of the carpals and metatarsals. Only 19 affected families worldwide have been recorded in medical literature. It is associated with a heterozygous base pair substitution of A to G in position 404–406, located on intron 5 in the LMBR1 gene.
Begin with the source’s own compact description: “Tibial hemimelia-polysyndactyly-triphalangeal thumb syndrome” is medical condition. The dossier treats that line as a proposition to test through Tibial, hemimelia-polysyndactyly-triphalangeal and thumb, not as a finished interpretation.
Why this record matters
The phrase “medical condition” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated May 2, 2026. The linked authority identifier is Q56014402. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
