During the past 2 years, she has had two long bone fractures. She is at the 5th percentile for height and 20th percentile for weight. Her right lower leg is diffusely erythematous. The patient withdraws and yells when her lower leg is touched. A photograph of her face is shown. An x-ray of the right lower leg shows a transverse mid-tibial fracture with diffusely decreased bone density. Which of the following is the most likely cause of this patients symptoms?? A: Type 3 collagen defect, B: Type 5 collagen defect, C: Type 1 collagen defect, D: Type 4 collagen defect, E: Type 2 collagen defect,  <response>: Based on the information provided, this appears to be a case of a 4-year-old girl with a history of multiple long bone fractures, short stature, and a new transverse mid-tibial fracture with decreased bone density. She also has facial features suggestive of an underlying genetic disorder. The pattern of recurrent fractures and decreased bone density points towards a disorder of bone fragility, likely related to abnormal collagen production. Of the collagen types listed, type 1 collagen is the most abundant in bone, so a defect in type 1 collagen production would be the most likely cause of her symptoms.C: Type 1 collagen defect
