**Question:** Which of the following syndrome is most commonly associated with clefts of lip and palate

A. Cleft Lip and Palate Syndrome (CLPS)
B. DiGeorge Syndrome
C. Cleft Lip and Palate with Cleft Hand Syndrome (CLPSH)
D. Cleft Lip and Palate with Cleft Foot Syndrome (CLPFS)

**Correct Answer:** C. Cleft Lip and Palate with Cleft Hand Syndrome (CLPSH)

**Core Concept:**
Cleft Lip and Palate (CLP) is a congenital birth defect characterized by a split or opening in the upper lip and roof of the mouth. It can be isolated (CLP without other associated anomalies) or part of a syndrome. The most common syndromes associated with cleft lip and palate include:

1. Cleft Lip and Palate Syndrome (CLPS): This refers to isolated cleft lip and palate without any other associated anomalies.
2. DiGeorge Syndrome: This syndrome is characterized by abnormalities in chromosome 22, which affects the thymus gland, parathyroid gland, and development of the heart and palate. DiGeorge Syndrome is not commonly associated with cleft lip and palate.
3. Cleft Lip and Palate with Cleft Hand Syndrome (CLPSH): This is a rare syndrome associated with cleft lip and palate and other hand anomalies, such as missing or malformed fingers, thumb, and/or ulnar deviation of the fingers. This option is the correct answer as it represents a syndrome commonly associated with cleft lip and palate.
4. Cleft Lip and Palate with Cleft Foot Syndrome (CLPFS): This syndrome is extremely rare and not commonly associated with cleft lip and palate. It is characterized by cleft lip and palate, and additional foot defects such as polydactyly (extra toes) and talipes (clubfoot).

**Why the Correct Answer is Right:**

Cleft Lip and Palate with Cleft Hand Syndrome (CLPSH) is the correct answer because it is the most common syndrome associated with cleft lip and palate. The syndrome is characterized by the combination of cleft lip and palate along with hand anomalies, such as missing or malformed fingers, thumb, and/or ulnar deviation of the fingers.

**Why Other Options are Incorrect:**

- DiGeorge Syndrome (Option B): While DiGeorge Syndrome does involve cleft lip and palate, it is associated with abnormalities in chromosome 22 and involves different clinical features, making it less likely compared to CLPSH.

- Cleft Lip and Palate with Cleft Foot Syndrome (Option D): This syndrome is extremely rare and not commonly associated with cleft lip and palate. It is characterized by cleft lip and palate along with foot defects such as polydactyly (extra toes) and talipes (clubfoot).

**Clinical Pearl:**

Cleft Lip and Palate with Cleft Hand Syndrome (CLPSH) is an important concept to remember for students preparing for medical exams like NEET,
