The case of trismus-pseudocamptodactyly syndrome due to rare variant in MYH8 gene

https://doi.org/10.25557/2073-7998.2024.08.58-62

Abstract

Trismus-pseudocamptodactyly syndrome (TPS, distal arthrogryposis type 7) is a rare disease with autosomal dominant inheritance from the group of distal arthrogryposis. The most characteristic clinical manifestations of TPS are trismus and limited extension in the interphalangeal joints of the hand during dorsiflexion of the wrist (pseudocamptodactyly). The cause of the disease is the pathogenic
variant c.2021G>A (p.Arg674Gln) in the MYH8 gene, which has been identified in all cases of the syndrome described in the scientific medical literature. This study presents a new case of TPS caused by the rare variant NM_002472.3 (MYH8): c.2020C>T (p.Arg674Trp, rs762523289).
