Added comment: HGNC approved gene symbol - NARS1

Both mono allelic and biallelic variants associated with a progressive neurological disorder with onset in infancy. Antenatal features reported.

PMID 32738225 - reports roband with de novo heterozygous variant - IUGR and oligohydramnios noted prenatally. At birth noted to have low weight and OFC for gestational age. Proband with homozygous variant diagnosed with microcephaly, seizures and FTT in the neonatal period. Proband with compound het variants born with a low weight (-2.38 SD) and height (-3.76 SD) for gestational age. Review of supplementary material table - microcephaly at birth reported in 17 unrelated families.
