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);
