Can G6PD Deficiency Happen Without Family History?
Yes, it is possible but uncommon. Here’s a quick summary:
1. Inheritance:
• G6PD deficiency is usually inherited in an X-linked recessive pattern. Males are primarily affected, while females are often carriers.
2. De Novo Mutations:
• Spontaneous mutations in the G6PD gene can cause the condition, even without inheritance from parents.
3. Unrecognized Carriers:
• Female carriers may be asymptomatic and unaware they carry the gene, passing it to their children.
4. Missed Family History:
• Mild or undiagnosed cases in family members may lead to an apparent lack of family history.
5. Mixed Ancestry:
• The condition may appear sporadically due to genetic mixing in regions where G6PD deficiency is common.
Key Takeaway:
While family history is common, sporadic cases due to new mutations or unrecognized carriers can occur. Testing confirms the diagnosis.
