Fetal anomalies v1.438 AMOT Rylee Peters gene: AMOT was added
gene: AMOT was added to Fetal anomalies. Sources: Literature
Mode of inheritance for gene: AMOT was set to X-LINKED: hemizygous mutation in males, biallelic mutations in females
Publications for gene: AMOT were set to 40892511
Phenotypes for gene: AMOT were set to Congenital hydrocephalus MONDO:0016349, AMOT-related
Review for gene: AMOT was set to AMBER
Added comment: 1x family with isolated X-linked congenital hydrocephalus – clinical presentation considered late, identified in the third trimester. Variant segregated with disease in 6x affected hemizygous males (4x live-born and 2x terminated male fetuses). Carrier females are apparently normal (no brain MRI was performed).

Exome sequencing identified start loss variant, c.2T>C p.(Met1Thr). Functional analyses identify that the variant results in a protein lacking 91 amino acids from the N-terminus and leads to abnormally increased AMOT protein levels (increased stability due to loss of degradation signals), which disrupts epithelial and endothelial barrier integrity.

Added comment: PMID: 40965981 27 individuals with abnormal prenatal ultrasound in thirteen (48%) including short femora, IUGR, hydramnios, increased nuchal translucency, asymmetry of heart cavities, and bilateral hydronephrosis. Skeletal anomalies were seen in 24 (89%), short stature/limbs in 63%, facial dysmorphism 25 (93%), developmental delay in 78%, behavioral problems in 30% and ID in 26% generally mild/moderate, 43% had variable brain MRI abnormalities. additional features included skin, nail, and hair anomalies (52%), dental anomalies (37%), ophthalmological findings (44%), and cardiovascular defects (22%).

Variants a mix of missense and startloss, and were confirmed de novo in 23/17 cases.

Various functional studies showed reduced nuclear localization and enhanced cytoplasmic retention, with start-loss variants also leading to increased protein stability.

Added comment: PMID: 34170319 - Ravindran et al 2021 report two pedigrees with an MCPH-SCKS phenotype spectrum without SRNS. In the first family, a 9 yo female, with consanguineous parents, is reported to have a missense variant in NUP85 (c.932G > A; p.R311Q). Intrauterine growth restriction was noticed. At birth microcephaly was observed (OFC < 3rd centile, < −3.6 SD) as well as hypotrophy [weight −2.8 SD), length 45 cm (−2.7 SD), both <3rd centile], facial dysmorphism, syndactyly, long and thin fingers, and bilateral pes adductus. She has severe developmental delay with strongly delayed motor milestones and absent speech. Drug-resistant, genetic epilepsy with focal-onset seizures started in the first year of life. She had no clinical, laboratory or radiological findings indicative of kidney dysfunction. In the second family, compound heterozygous missense variants in NUP85 were detected (c.1109A > G, c.1589 T > C;p.N370S, p.M530T ) in a fetus. MRI of the fetal brain at 24 + 2 GW indicated complete agenesis of the corpus callosum, abnormal sulcation in the left frontal lobe, nodularity of the frontal horn and trigone with focal puckering of the left lateral ventricle.

Variants in this gene are also associated with nephrotic syndrome.

Pehlivan et al. 2019 (PMID:31230720) identified the third case of arthrogryposis in a child who harboured a previously unreported homozygous variant (c.782G>A; p.Gly261Asp) in this gene. Parents were heterozygous carriers. Functional studies were not performed.

Reinstein et al. (2018) used WES in a large consanguineous Israeli Arab kindred consisting of 16 patients affected with the neurogenic type of arthrogryposis multiplex congenita. They identified a homozygous missense (V98E) mutation in ERGIC1 gene, which segregated with the disorder in the kindred, and was not found in the ExAC database or in 212 ethnically matched controls. Functional studies of the variant and studies of patient cells were not performed. ERGIC1 encodes a cycling membrane protein which has a possible role in transport between endoplasmic reticulum and Golgi.

Marconi et al (2021) used genome sequencing in a consanguineous family with 2 affected siblings presenting congenital arthrogryposis and some facial dysmorphism. They identified a homozygous 22.6 Kb deletion encompassing the promoter and first exon of ERGIC1. mRNA quantification showed the complete absence of ERGIC1 expression in the two affected siblings and a decrease in heterozygous parents.

Fetal anomalies v0.610 CRLF1 Zornitza Stark edited their review of gene: CRLF1: Added comment: Micrognathia, camptodactyly are features.

Crisponi/cold-induced sweating syndrome is an autosomal recessive disorder characterized in the neonatal period by orofacial weakness with impaired sucking and swallowing resulting in poor feeding necessitating medical intervention. Affected infants show a tendency to startle, with contractions of the facial muscles in response to tactile stimuli or during crying, trismus, abundant salivation, and opisthotonus. During the first year, most infants have spiking fevers. These features, referred to as 'Crisponi syndrome' in infancy, can result in early death without advanced care. After the first 2 years, the abnormal muscle contractions and fevers abate, and most patients show normal psychomotor development. From childhood onward, the most disabling symptoms stem from impaired thermoregulation and disabling abnormal sweating, which can be treated with clonidine. Patients have hyperhidrosis, mainly of the upper body, in response to cold temperatures, and sweat very little with heat. Other features include characteristic facial anomalies, such as round face, chubby cheeks, micrognathia, high-arched palate, low-set ears, and depressed nasal bridge, dental decay, camptodactyly, and progressive kyphoscoliosis.
