Which of the following may result in Seal like limbs deformity in new-born?
**Core Concept**
Seal-like limbs deformity in newborns is a rare congenital anomaly characterized by a condition where the limbs appear shortened and clubbed, resembling those of a seal. This condition is often associated with underlying musculoskeletal and neurological abnormalities.
**Why the Correct Answer is Right**
Fetal akinesia deformation sequence, also known as Pena-Shokeir syndrome, is a rare condition that can result in seal-like limbs deformity in newborns. This condition is caused by a failure of motor neurons to migrate and differentiate during embryonic development, leading to a lack of muscle tone and movement in the affected limbs. The absence of normal fetal movements and muscle activity during critical periods of development can result in the characteristic seal-like limbs deformity.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not directly related to the development of seal-like limbs deformity in newborns. While it may be a congenital anomaly, it is not specifically associated with the characteristic seal-like limbs deformity.
* **Option B:** This option is incorrect because it is not a known cause of seal-like limbs deformity in newborns. While it may be a congenital anomaly, it does not have a direct association with the characteristic seal-like limbs deformity.
* **Option C:** This option is incorrect because it is not a known cause of seal-like limbs deformity in newborns. While it may be a congenital anomaly, it does not have a direct association with the characteristic seal-like limbs deformity.
**Clinical Pearl / High-Yield Fact**
Fetal akinesia deformation sequence, also known as Pena-Shokeir syndrome, is a rare condition that can result in seal-like limbs deformity in newborns. It is essential to recognize this condition early in life to provide appropriate management and support for the affected individual.
**Correct Answer:** D
