Genes affected
ERMARD (HGNC:21056): (ER membrane associated RNA degradation) The protein encoded by this gene contains 2 transmembrane domains near the C-terminus and is localized in the endoplasmic reticulum. Knockout of this gene in developing rat brain showed that it may be involved in neuronal migration. Mutations in this gene are associated with periventricular nodular heterotopia-6 (PVNH6). Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2013]

Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 17, 2023The c.143C>T (p.T48I) alteration is located in exon 2 (coding exon 2) of the ERMARD gene. This alteration results from a C to T substitution at nucleotide position 143, causing the threonine (T) at amino acid position 48 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
