Added comment: i) PMID: 33772059- An Iranian family with RPL (Fam 94947) without fetal autopsy carrying homozygous missense p.1250T>M. The parents were both carriers with a history of cardiac events in the family. This variant has been reported to cause long QT syndrome 3 (LQT3) (#603830) in the heterozygous state. Homozygous mutations in SCN5A in mice cause intrauterine lethality mostly during organogenesis due to heart defects (PMID: 11972032).

ii) PMID: 32421437- de novo SCN5A variants in four cases which all died and three of them died in utero.

iii) PMID: 23571586- 5 intrauterine fetal deaths hosted SCN5A rare nonsynonymous genetic variants (p.T220I, p.R1193Q, involving 2 cases, and p.P2006A, involving 2 cases).

iv) PMID: 15184283- A case of recurrent third-trimester fetal loss and maternal mosaicism for long-QT syndrome- low level mosaic R1623Q present in mom and cord blood from the third fetus also harbored the mutant allele, suggesting that all 3 cases of late-term fetal distress resulted from germ-line transfer of the LQTS-associated mutation.
