Genes affected

MYRF (HGNC:1181): (myelin regulatory factor) This gene encodes a transcription factor that is required for central nervous system myelination and may regulate oligodendrocyte differentiation. It is thought to act by increasing the expression of genes that effect myelin production but may also directly promote myelin gene expression. Loss of a similar gene in mouse models results in severe demyelination. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Nov 2014]

TMEM258 (HGNC:1164): (transmembrane protein 258) Involved in protein N-linked glycosylation. Located in endoplasmic reticulum. Part of oligosaccharyltransferase I complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Benign. Variant got -14 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
