| A form of congenital disorders of N-linked glycosylation with characteristics of psychomotor delay-dysmorphism (pectus carinatum, dorsolumbar kyphosis and severe scoliosis, short distal phalanges, genua vara, pedes planovalgi syndrome) with postnatal growth deficiency and major skeletal involvement. Additional features include facial dysmorphism (midface hypoplasia, internal strabism of the right eye, low-set ears, moderately high arched palate, small teeth), nephrotic syndrome, cardiac defects, and feeding problems. The disease is caused by mutations in the gene TMEM165 (4q12). |
