" /> Short-rib thoracic dysplasia 6 with or without polydactyly - CISMeF





Preferred Label : Short-rib thoracic dysplasia 6 with or without polydactyly;

Symbol : SRTD6;

CISMeF acronym : SRPS2A; SRTD6;

Type : Phenotype, molecular basis known;

Alternative titles and symbols : Srps, type II; Polydactyly with neonatal chondrodystrophy, type II; Majewski syndrome; Short rib-polydactyly syndrome, type iia; Short rib-polydactyly syndrome, type II; SRPS2A;

Description : The diagnostic criteria for short rib-polydactyly type II (Majewski syndrome) include short and narrow thorax, horizontally oriented ribs, short tubular bones with smooth ends, ovoid tibiae that are shorter than the fibulae or tibial agenesis, and pre- and/or postaxial polysyndactyly (summary by El Hokayem et al., 2012). The short rib-polydactyly syndromes (SRPSs) are a group of autosomal recessive lethal skeletal dysplasias characterized by markedly short ribs, short limbs, polydactyly, and multiple anomalies of major organs, including heart, intestines, genitalia, kidney, liver, and pancreas. Five types have been distinguished: SRPS I (Saldino-Noonan type; 263530), SRPS II (Majewski type), SRPS III (Verma-Naumoff type; 263510),;

Inheritance : Autosomal recessive; Digenic recessive;

Molecular basis : Caused by mutation in the never in mitosis gene A-related kinase 1 gene (NEK1, 604588.0001); Caused by simultaneous heterozygous mutation in both the never in mitosis gene A-related kinase 1 gene (NEK1, 604588.0003) and the dynein, cytoplasmic-2, heavy chain-1 gene (DYN2CH1, 603297.0016);

Prefixed ID : #263520;
