Review for gene: KIDINS220 was set to GREEN
Added comment: Associated with Spastic paraplegia, intellectual disability, nystagmus, and obesity #617296 in OMIM for monoallelic cases.

3 biallelic cases associated with cerebral ventriculomegaly and limb contractures, plus a mouse model that shows some phenotypic overlap:

PMID: 32909676 - El-Dessouky et al 2020 - report a consanguineous family of Egyptian origin with several miscarriages. Prenatal ultrasonography revealed limb contractions and ventriculomegaly aswell as cerebellar anomalies, cardiac anomalies and hydrops fetalis. Using WES a homozygous deleterious frameshift variant (c.208del; p.Asp70Ilefs*18) in KIDINS220 gene was identified. Both parents were heterozygous for this variant.

PMID: 33205811 - Jacquemin et al 2021 - report a consanguineous family of Pakistani origin in which 3 fetuses presented with brain ventriculomegaly and limb contractures. Autopsy of one fetus identifed bilateral club feet and club hands. They were found by WES to share a very rare homozygous variant of KIDINS220 (c.2327_2336del, Gln713_Leu715del). Parents and healthy siblings were heterozygous for this variant. Severe ventriculomegaly was diagnosed as early as 14 weeks. Binding of KIDINS220 to TrkA is decreased by the deletion mutation.

PMID: 28934391 - Mero et al 2017 - report a consanguineous couple in which 4 fetuses presented with enlarged cerebral ventricles and limb contractures. Exome sequencing in two of the fetuses found a shared homozygous frameshift variant in exon 24 in KIDINS220 ((NM_020738:c.3394_3403del; p.Gln1132Serfs*30). Healthy family members were either carriers or homozygous for the wild-type allele. It is thought that the variant leads to NMD and complete loss of KIDINS220 protein.

PMID: 22048169 - Cesca et al 2011 - report a Kidins220 mutant mouse. Kidins220 -/- mice die at late stages of gestation and show extensive neuronal cell death in the central and peripheral nervous systems, as well as heart malformations.
