On this page, you will find information about genetic changes that were identified in a UDN participant.

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

Changes in this gene were identified in a female, age 3 with pontocerebellar hypoplasia, type 2D (read full description).

Date of Report

Nov 09, 2017

Full Name

Sep (O-phosphoserine) tRNA:Sec (selenocysteine) tRNA synthase

Chromosome 4 (4p15.2)


The SEPSECS gene codes for an enzyme important in the formation of a transfer RNA (tRNA). This tRNA is involved in the production of a protein building block called selenocysteine (MedlinePlus Genetics).
