42yr old female suffering with multiple ailments
I have been given this case to solve and interpret to enhace my competency and as an attempt to understand the topic of "patient clinical data analysis"
You can find the entire clinical problem of the patient in this link https://classworkdecjan.blogspot.com/2019/05/42-f-with-severe-regular-edema-with_17.html
Priority of her complains according to my analysis
1) Severe headache associated with visual aura.
- loss of function & numbness on left side
- Falling to left side
- Vertigo
- csf rhinorrhea from left nostril
- Aggravated by :stress,mensus, birth control pills
- Headache was relieved by taking medication (triptans)
Diagnosis :
- Most probably hemiplegic migraine
Differential diagnosis may be
- Space occupying lesion on right side.
- Increased ICT
- Secondary headache syndrome
- Cerebral vasculitis ( presents as headache & neurological deficit )
HEMIPLEGIC MIGRAINE
What Causes Them?
So far, researchers have found four genes linked with hemiplegic migraine:
- CACNA1A
- ATP1A2
- SCN1A
- PRRT2
- CACNA1A codes for CAV2.1 calcium channels in brain . Mutation in that gene impairs the ca+2 channels influx there by impairing the release of neurotransmitors(serotonin) & may cause migraine attack.
- * CACNA1A gene mutation is associated with episodic ataxia
- This may explains why she gets migraine attack & ataxia
Reference :
https://ghr.nlm.nih.gov/gene/CACNA1A
FURTHER INVESTIGATIONS :
- To rule out space occupying lesions - neuro imaging mri
- For ICT - lumbar puncture
- Neurological examination
Left hand numbess May be due to her T1 vertebral hemangioma compressing only left side
2) COGNITIVE IMPAIRMENT
There are plethora of reasons for cognitive deficits.
- In this patient I think MTHFR GENE mutation is responsible.
MTHFR gene mutation ----> increase in homocysteinaemia ----> increased risk of osteopososis , stroke , Alzeimers disease.
- Homocysteinaemia causes ectopis lentis. This may be the reason for her poor sight.
This may also explain the multiple fractures , memory loss in this patient.
- MTHFR MUTATION ---> impaired metabolism of vitB12 & folic acid --->psychomotor problems.
- MTHFR MUTATION is associated with increased risk of ADHD & AUTISM.Migriane with aura
This patient is diagnosed with ADHD & AUTISM at 35 yrs.
Reference https://www.psychologytoday.com/us/basics/adhd
INVESTIGATIONS :
- serum vit b12 levels analysis
- Peripheral smear
- Increased homocysteine in urine
- G6pd deficiency ----> hemolysis --->
Increase bilirubin---> increased urobilin ---> toxic injury to kidney --->
Acute kidney injury ---> repetitive kidney infections , Edema , oliguria
- May also be due to malnutrition and decreased protein intake as she has less food intake
DIFFUCULTY IN RESPIRATION
May be due to her hiatal hernia
EXERCISE INDUCED FATIGUE
May be due to AMPD 1 MUTATION.
AMPD 1 MUTATION ----> AMP deaminase disfunction -----> impairs the ability of muscles to produce energy
SLEEPLESSNESS
The reason for sleep disturbances could be G6PD deficiency: G6PD deficiency results in impaired glycolysis. As a result Glycine (inhibitory neurotransmitter) is not produced.2. As she was diagnosed with ADHD(Attention Deficit Hyperkinetic Disorder), it could also be a reason for sleep disturbances.Treatment:- she is taking L Serine(orally)L Serine converts to Glycine invivo, which is an inhibitory neurotransmitter.
Increased pain tolerance
Differential diagnosis :
- Dissociative disorders
- Fibromyalgia ( her mother is known case of fibromyalgia )
- Hereditary sensory autonomic neuropathy type -2 as seen in WNK1 MUTATION
- prader willi syndrome
WNK1 MUTATION :different WNK1 isoforms are important in several functions in the body, including blood pressure regulation and pain sensation
- HSAN TPYE 2 associated with wnk1 mutation

PRADER WILLI SYNDROME (PWS) :
PWS is caused by deletion of paternal chromosome 15
PWS CLINICAL FEATURES | REASON in pws | SYMPTOM IN PATIENT |
Sleep distubances | MAGEL'S 2 GENE DELETION which is responsible for regulating circadian rhythmes | present. |
Hypotonia | Megel's 2 gene deletion . https://www.google.com/amp/s/www.fpwr.org/fpwr-funded-projects/loss-of-magel2-and-hypotonia-in-prader-willi-syndrome%3fhs_amp=true | present |
Scoliosis | Due to low muscle tone | present |
Pcos | due to adrenarche . Adrenarche shows incresed DHEAS . https://en.m.wikipedia.org/wiki/Adrenarche | present pcos is may be responsible for her ectopic pregnancy. she also has abnormal hair growrh ( hirsutism) |
High pain Tolerance | NECDIN gene deletion which plays a role in terminal differentiaon of neurons https://www.genecards.org/cgi-bin/carddisp.pl?gene=MAGEL2#summaries | present |
Autism & ADHD | hypothalmus is affected leading to behavioral changes ( MEGEL 2 GENE DISFUNCTION ) | PRESENT |
Insatietable hunger & obesity | present | Absent patient has anorexia & specific reason for it should be ruled out. Due to anorexia there is no obesity |
DYSLEXIA is diagnosed in this patient. Dyslexia most of times associated with ADHD & autism .
Genetics : associated with DYX1C1 present on chromosome 15 .
Reference https://en.m.wikipedia.org/wiki/Dyslexia
In pws - chromosome 15 deletion.
- MAGEL 2 belong to MAGE family. (melanoma antigen gene )
- MEGEL2 DISFUNCTION present in PWS
- MAGE mutations are common in melanoma.
- Reference https://pubmed.ncbi.nlm.nih.gov/20862285/
- Pt was diagnosed with melanoma . This may explain the coorelation .
There are many similariteis in clinical features of pws & this pt. But not sure because most important clinical feature hyperphagia & obesity are absent in this patient.
Full genome study is required for confirmation of PWS
FURTHER INVESTIGATIONS :
- DOLORIMETRY - assess pain threshold
- Pain intensity scales
- Full genome study
RECURRENT MOUTH ULCERS
- Mouth ulcers are relapsing
- May be autoimmune in origin
- Associated with arthritis - patient has hip & knee joint pain.
Differential diagnosis :
- Behcet's disease
- Reactive arthritis
Pt is diagnosed with behcet's disease recently.
BEHCET'S DISEASE :
- Associated with HLA - B51
- It is thought to be an inflammatory reaction triggered by streptococcus in genitically predisposed individuals ( she reported she has recurrent streptococcal infections for which she also got vaccinated )
pt. May Presents with mouth ulcers , arthritis , vasculitis , increased ICT
- Vasculitis ----> may occlude the vessels supplying optic nerve ----> acute optic neuropathy
This may explain the transient vision loss in this patient.
- There may be increased ICT secondary to cerebral vasculitis .
Cerebral vasculitis ---> increased ICT -->Headache & CSF rhinnorhea.
This may explain that pt has a episode of headache associated CSF rhinorrhea

FURTHER INVESTIGATION
- fundoscopy for optic nerve
- Csf analysis by lumbar puncture
- Pathergy test
