SPTSSA

On this page, you will find information about a genetic change that was identified in a UDN participant. We are trying to find others with the same or similar condition.

Sharing information on this website is not a requirement of UDN participation. Only descriptions about participants who give explicit consent will appear here.

A change in the SPTSSA was identified in a female, age 9, with severe global developmental delay, muscle tone abnormalities, spasticity and cerebral folate deficiency (read full description).

Date of Report

Aug 20, 2020

Full Name

Serine palmitoyltransferase small subunit A

Location

Chromsome 14 (14q13.1)

Function

SPTSSA codes for a protein subunit responsible for stimulating serine palmitoyltransferase activity, which initiates an important rate-limiting step in sphingolipid biosynthesis (Han et al., 2009).
