Holoprosencephaly sequence.

Area of Science:

• Developmental Biology
• Medical Genetics

Background:

• Holoprosencephaly (HPE) is a congenital disorder characterized by the incomplete separation of the embryonic forebrain.
• It presents a spectrum of facial and cerebral malformations, with subtypes including lobar, semi-lobar, alobar, and middle inter-hemispheric variant (MIHF).
• HPE has a heterogeneous etiology, involving teratogens, chromosomal abnormalities, and single gene mutations, leading to significant early morbidity and mortality.

Observation:

• This case report focuses on a male newborn diagnosed with holoprosencephaly.
• The infant presented with distinct facial anomalies, specifically a median cleft palate and absent nasal bones.
• Associated chromosomal abnormalities were identified in the neonate.

Findings:

• The diagnosis of holoprosencephaly was confirmed in the newborn male.
• The presence of median cleft palate and absent nasal bones are key clinical findings.
• The identified chromosomal abnormalities contribute to the understanding of HPE etiology in this case.

Implications:

• This case highlights the complex presentation of holoprosencephaly, emphasizing the link between facial dysmorphism and underlying genetic factors.
• Understanding the specific chromosomal abnormalities associated with HPE is crucial for genetic counseling and family planning.
• Further research into HPE etiology and management is warranted to improve outcomes for affected individuals.
