Comment :
homozygosity for a 4-bp insertion (c.222_223insCATG, NM_024587.4) in exon 3 of the TMEM53 gene, affecting transcripts T.1 and T.2. The insertion causes a frameshift predicted to result in a premature termination codon, Val75HisfsTer26 in T.1 and Val2HisfsTer26 in T.2, with both proteins lacking the transmembrane domain. The unaffected first-cousin parents were heterozygous for the insertion, which was not found in the ExAC or gnomAD databases. Immunocytochemistry in MG63 cells indicated that the T.1 Val75HisfsTer26 mutant failed to target the nuclear envelope, where the normal isoforms were localized. The T.2 Val2HisfsTer26 mutant was expressed as mRNA, but not on the protein level.
