Report of 2 fetal cases in a consanguineous Pakistani family. Exome seq revealed a homozygous nonsense variant c.283C>T, p.(Arg95Ter) in BORCS5 (NM_058169.4). Individuals showed neuroaxonal dystrophy with osteopetrosis.

PMID: 40385417 Mencacci et al., 2025 - pre-print
Report of 12 individuals from 7 unrelated families with biallelic BORCS5 variants (NM_058169.4): two missense variants (c.284G>A, p.R95Q; c.296A>C, p.H99P) and four LoF alleles (c.203–1G>T, p.?; c.316delG, p.A106Pfs*20; c.382_383delAG, p.L128Vfs*86; c.417C>G, p.Y139*).
Table 1 = phenotypic spectrum of 6 individuals from families 1-4: profound ID (6/6), severe spasticity (6/6), seizures (6/6), hyperreflexia (6/6), Parkinsonism/dystonia (3/6), limb contractures (5/6), optic atrophy (5/6), abnormal brain MRI including cerebral atrophy and/or corpus callosum agenesis (5/6), microcephaly (6/6 - severity not stated), muscle atrophy (5/6). Infantile onset.
Neuroimaging in 5 cases showed cerebral atrophy, white matter loss, hypomyelination, small T2-hypointense thalami, thin brainstem, and optic nerve atrophy.

PMID: 27435318 Charng et al., 2016
Patient BAB6775 homozygous for NM_058169.4 BORCS5: c.203-1G>T, with DD, microcephaly, seizures, cortical malformations, polymicrogyria, agenesis of corpus callosum. Also reported with more details in PMID:40385417 (do not count).

Additional functional evidence: Zebrafish borcs5 knockout leads to neurodevelopmental defects:microcephaly, ventriculomegaly, movement disorders and epilepsy.

BORCS5 is not yet associated with a disease in OMIM (accessed 20th Feb 2026).

Childhood onset hereditary spastic paraplegia v3.17 MAG Arina Puzriakova Added comment: Comment on list classification: There is sufficient evidence to promote this gene to Green at the next GMS panel update.

At least 12 individuals from 8 families have been identified with biallelic variants in this gene. Clinical features are characterised by spasticity (9/13), neuropathy (8/13), optic atrophy (7/13), variable cognitive deficits (7/13), and cerebellar signs (10/13) including ataxia in some (8/13) although 3/10 showed normal brain MRI results.

Childhood onset hereditary spastic paraplegia v2.115 IFIH1 Arina Puzriakova Added comment: Comment on list classification: Spasticity can be a prominent feature of Aicardi-Goutières syndrome (OMIM:615846) and has been reported as an early presenting sign in some cases. There has also been a case of spastic paraplegia without other common manifestations such as abnormal brain imaging and impaired cognitive development.

Overall there is value in including IFIH1 on this panel and therefore this gene should be promoted to Green at the next GMS panel update.
Childhood onset hereditary spastic paraplegia v2.87 PI4KA Ivone Leong changed review comment from: This gene is associated with a relevant phenotype in OMIM and Gene2Phenotype.

PMID: 25855803. From OMIM: "3 fetuses were all diagnosed in utero with multiple congenital anomalies resulting in the termination of pregnancy between 16 and 34 weeks' gestation. All fetuses had bilateral perisylvian polymicrogyria and cerebellar hypoplasia or dysplasia. One had a small pons. Additional features included severe talipes equinovarus, externally rotated hips, and variable contractures of the limbs or fingers."

PMID:34415322. 10 patients from 10 unrelated families with biallelic varaints in PI4KA. Patients showed a spectrum of severe global neurodevelopmental delay (8/10 moderate to severe ID), hypomyelination, cerebellar hyoplasia (1/10), cerebellar atrophy (5/10), bilateral perisylvian polymicrogyria (1/10), immunological problems (hypogammaglobulinaemia, lymphopaenia, and autoimmune neutorpaenia - 4/10), bowl dysfunction (4/10). Age of onset ranged from newborn to 17 years.
