Often they become very irritable starting in the second or third month of life.[ghr.nlm.nih.gov]
The single affected individual described by Siu et al [2010] had irritability and profound developmental delay. The Amish patients were able to breast/bottle feed early on, but developed severe irritability and seizures.[ncbi.nlm.nih.gov]
Case studies report that the infant has seizures early on, is cold all the time, becomes irritable at ages 12 - 16 weeks, and dies before the age of one year.[owlcation.com]
Physical therapy may alleviate contractures or other secondary neurologicmanifestations. Infectious illnesses are managed to minimize acidosis. GENETIC COUNSELING: Amish lethal microcephaly is inherited in an autosomal recessive manner.[ncbi.nlm.nih.gov]

Etiology All affected infants are homozygous for the same mutation of the SLC25A19 gene on chromosome 17 (17q25.3). Genetic counseling The condition follows an autosomal recessive pattern of inheritance.[rarediseases.info.nih.gov]
Etiology Microcephaly has been stratified and studied differently based on the etiology and the timing of onset.[mdpi.com]
