June 2026 Research Update

At a glance

Newborn diagnosis

Genetic testing diagnosed Kabuki syndrome type 1 in a newborn.

New KMT2D variant

A new truncating KMT2D variant adds to known gene changes.

Heart and chest findings

The newborn had severe heart obstruction and chest-related problems.

Early severe presentation

This single newborn case adds detail on very early, severe Kabuki type 1 presentations. Because it is one report without parental testing, it cannot show how common this pattern is.

Overview

This month, the Kabuki syndrome research literature was small and focused on one detailed newborn case.

The report described Kabuki syndrome type 1 being recognized very early in life in a baby with severe problems affecting the heart and chest. The pregnancy and newborn period included major fluid buildup before birth and complex heart obstruction that required a duct-dependent circulation.

Genetic testing identified a previously unreported truncating (gene-shortening) change in the KMT2D gene. The case also included a right Morgagni hernia, which is a type of diaphragmatic hernia. Together, these details expand the reported range of KMT2D gene changes and the kinds of early-life presentations that can occur in Kabuki syndrome type 1.

The baby died at 1 month. This reflects the severity of this specific presentation rather than a typical outcome. Because this is only one case and parental genetic testing was not reported, it cannot show how common this combination is or whether it follows a similar course in other children.

Research topics this month

Limitations

• Only one published case report was available this month.
• Parental genetic testing was not reported, so inheritance of the KMT2D change was unclear.
• A single case cannot estimate how common this severe newborn presentation is.
