Genes affected
RXYLT1 (HGNC:13530): (ribitol xylosyltransferase 1) This gene encodes a type II transmembrane protein that is thought to have glycosyltransferase function. Mutations in this gene result in cobblestone lissencephaly. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, May 2013]
RXYLT1-AS1 (HGNC:48910): (RXYLT1 antisense RNA 1)

This variant, c.1153_1158del, results in the deletion of 2 amino acid(s) of the TMEM5 protein (p.Phe385_Ile386del), but otherwise preserves the integrity of the reading frame. This variant is present in population databases (rs767728184, gnomAD 0.008%). This variant has not been reported in the literature in individuals affected with TMEM5-related conditions. ClinVar contains an entry for this variant (Variation ID: 565680). Experimental studies and prediction algorithms are not available or were not evaluated, and the functional significance of this variant is currently unknown. In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. -
