Additional variable features are visual impairment and arachnodactyly. Most patients die in early childhood. GAMOS7 inheritance is autosomal recessive. MalaCards based summary : Galloway-Mowat Syndrome 7, is also known as gamos7. [malacards.org]
Skeletal abnormalities such as arachnodactyly or camptodactyly (Fig. 2) were also noted in all patients. Other dysmorphisms included a high arch palate (5/6). [ojrd.biomedcentral.com]

Hypertelorism
Most patients show facial dysmorphism characterized by a small, narrow forehead, large/floppy ears, deep-set eyes, hypertelorism and micrognathia. Additional variable features are visual impairment and arachnodactyly. [malacards.org]
The consistent facial dysmorphic features included large and floppy ears, micrognathia, hypertelorism, microphthalmia, sunken eyeballs, coarse hair, a narrow or receding forehead, a beak nose, and prominent glabella with a broad nasal bridge. [ojrd.biomedcentral.com]

Narrow Forehead
Most patients show facial dysmorphism characterized by a small, narrow forehead, large/floppy ears, deep-set eyes, hypertelorism and micrognathia. Additional variable features are visual impairment and arachnodactyly. [malacards.org]
Physical features may include malformations of the head and facial (craniofacial) area including microcephaly, which can be present at birth or develop shortly after birth, an abnormally high, narrow forehead and unusually small jaw bones (micrognathia [rarediseases.org]

Galloway-Mowat syndrome 7: A form of Galloway-Mowat syndrome, a severe renal-neurological disease characterized by early-onset nephrotic syndrome associated with microcephaly, central nervous system abnormalities, developmental delays, and a propensity for seizures [malacards.org]
Therapy with anti-seizure (anticonvulsant) drugs may be prescribed for affected individuals who experience seizures to help prevent, reduce, or control seizures. [rarediseases.org]
However, the onset, type, and frequency of the seizures as their response to therapy varied greatly between the patients as well. [ncbi.nlm.nih.gov]
The main clinical manifestations included postnatal microcephaly, a coarse face, severe intellectual disability, seizures, cerebellar ataxia, optic atrophy, and late-onset nephrotic syndrome [4,5,6,7,8]. [ojrd.biomedcentral.com]

Workup
Clinical Testing and Workup In affected infants, symptoms associated with nephrotic syndrome may become apparent within days, weeks, months, or in some cases, years after birth. [rarediseases.org]
Workup included karyotype of 46,XX, and normal acylcarnitines, CPK (creatine phosphokinase), and mass spectrometric analysis of transferrin. [ncbi.nlm.nih.gov]

The patient from family 2286 was born at 37 GW by NSD following treatment for premature labor to double first-cousin parents. [ncbi.nlm.nih.gov]
The proteinuria was progressive and unresponsive to corticosteroid treatment, and this eventually resulted in massive proteinuria (range of urine protein to creatinine ratio, 20.4–740) and renal function impairment. [ojrd.biomedcentral.com]
Prognosis
Parents should talk to the physician and medical team about their child’s specific case, associated symptoms and overall prognosis. [rarediseases.org]
From a pathological point of view, Keith et al. showed that children with disordered neuronal migration tend to have a worse prognosis (true GAMOS), and those without gyral abnormalities have a better prognosis [19]. [ojrd.biomedcentral.com]
Prevention
Therapy with anti-seizure (anticonvulsant) drugs may be prescribed for affected individuals who experience seizures to help prevent, reduce, or control seizures. [rarediseases.org]
