- Pain
The clinical consequence of increased thickness of the skull include facial nerve palsy causing hearing loss, visual problems, neurological pain, and, very rarely, blindness as a consequence of optic atrophy. [abcam.com]
“Before a lot of us participated in these projects, very little about pain itself was known,” he said. [news.com.au]
Some patients have crises of pain of variable duration (hours-weeks); 58% have pain to bone percussion. [elsevier.es]
- Anemia
[…] nermann type Chondrodysplasia punctata, MT type Chondrodysplasia punctata, X-linked dominant type Chondrodysplasia punctata, X-linked recessive type Craniodiaphyseal dysplasia Dappled diaphyseal dysplasia Diaphyseal dysplasia Diaphyseal dysplasia with anemia [icd9data.com]
In other cases, transfusions to treat anemia and splenectomy to increase platelets may be recommended. Depending on the form of sclerosing bone dysplasia, treatment to correct hematologic issues may not be effective. [encyclopedia.com]
There may be spontaneous bleeding with anemia and recurrent infections. The neurological complications are blindness and deafness. Patients usually die in the first decade of life. [elsevier.es]
Generalized increase in density and thickness of the skull base is seen in fibrous dysplasia, Paget disease, anemias, fluorosis, hypothyroidism, hyperparathyroidism, hypervitaminosis D, idiopathic hypercalcemia, healing rickets, and some syndromes. [rrnursingschool.biz]

Though the precise function and working of SOST remains unknown, an inhibitory effect on bone formation can be proposed since pathophysiological analysis indicated that sclerosteosis is primarily a disorder of increased formation of normal bone ( 7 ). [academic.oup.com]
