A Newborn with Rare McKusick Syndrome

Area of Science:

• Genetics
• Pediatrics
• Medical Genetics

Background:

• McKusick-Kaufman Syndrome (MKKS) is a rare autosomal recessive disorder.
• It is characterized by polydactyly, hydrometrocolpos (HMC), and cardiac anomalies.
• Mutations in the MKKS gene are the underlying cause of this syndrome.

Observation:

• This report details a case of a neonate presenting with clinical features indicative of MKKS.
• The neonate exhibited characteristic genitourinary and digit abnormalities.
• Differential diagnosis considered Bardet-Biedl syndrome due to overlapping features.

Findings:

• The neonate displayed the hallmark polydactyly and genitourinary abnormalities associated with MKKS.
• Cardiac anomalies were also noted, consistent with the syndrome's presentation.
• Clinical diagnosis was supported by the constellation of symptoms.

Implications:

• Accurate diagnosis of MKKS is crucial for appropriate management and genetic counseling.
• Understanding the genetic basis aids in identifying at-risk families.
• Prompt identification allows for targeted treatment of manifestations and complications.
