Added comment: PMID 36996813
- Thirteen affected individuals, including four fetuses, from eight unrelated families, with homozygous loss-of-function-type variants in ESAM – 2 of the variants are frameshifts, 1x nonsense, 1x canonical splice.
- Affected individuals have profound global developmental delay/unspecified intellectual disability, epilepsy, absent or severely delayed speech, varying degrees of spasticity, ventriculomegaly, and ICH/cerebral calcifications, the latter being also observed in the fetuses.
- One of the frameshift variant c.115del (p.Arg39Glyfs*33), was detected in six individuals from four unrelated families from the same geographic region in Turkey (southeastern Anatolia), suggesting a founder effect.
- The c.451+1G>A variant was detected in three individuals from two independent families with the same ethnic origin (Arab Bedouin)
