A nih loh leh naupang tê têah hetiang chhinchhiahna i hmuh hian hlauhna leh lungkhamna nasa tak i neih hi thil pangngai a ni em? Vawiin hian hetiang huna i hriat reng tur genetic condition hmuh tur awm lo mahse pawimawh tak tak kan sawi dawn a ni. Hei hi Friedreich’s ataxia an ti a, a tawi zawngin `(FA)` emaw `(FRDA)` emaw an ti.

Friedreich-a Ataxia hi eng nge ni?

A awlsam zawngin Friedreich-a Ataxia hi genetic condition a ni a, thlah khat atanga thlah dangah a inthlak danglam zel a ni. Hei hian kan nervous system a ti chhe zauh zauh a, kan taksa chetna lamah harsatna a siam a ni. A bik takin kan taksa ruhte thunun theihna a tlahniam a ni. Hei hi ``Ataxia'' kan tih chu a ni.He natna hi hun kal zelah a zual zel thin.

A tam zawkah chuan heng symptoms te hi kum naupan lai atanga tan a ni. Chu chu naupan lai a ni. Mahse hei hi nervous system tichhe thei thil mai a ni lo. I ruhro, thinlung, leh pancreas ang chi hmunte pawh a nghawng thei bawk. Mahse chanchin lawmawm tak chu, i ngaihtuahna thiamna, chu chu i rilru lam theihna (Cognitive Functions) a nghawng lo tih hi a ni.

Friedreich’s ataxia hi hereditary ataxia chi khat a ni a, mahse a tlangpuiin a tlem hle. United States-ah chuan mi 50,000 zinga pakhat velin a nghawng a ni. Khawvel pumah mi 40,000 zinga pakhat velin a nghawng a ni. He natna hi kum 1863 khan doctor pakhat Nicholas Friedreich-a’n a hmuhchhuah leh a sawifiah hmasak ber a ni. Chuvang chuan a hming chawia sak a ni.

I fain kal a harsat tan emaw, a balance a hloh tan emaw a hlauhthawn hi thil pangngai a ni. "Hei hi eng chen nge a awm ang? Hei hian ka fa nun hi engtin nge a nghawng ang?" A tha ber chu heng natna hrang hranga specialist doctor pan hi a ni. Chutiang chuan i zawhnate chhanna i hmu thei a, he zinkawngah hian i mamawh tanpuina i hmu thei bawk.

Friedreich-a ataxia (FA) hi chi hrang hrang a awm em?

Ni e, "typical" Friedreich-a ataxia hi kum 25 hmain a lo lang tlangpui a, mahse, atypical chi dang pahnih a awm bawk. Hengte hi FA case zawng zawng zinga 15% vel an ni:

• Late-onset Friedreich’s ataxia (LOFA): Hetiang chi ah hian kum 25 hnuah a lan chhuah dan a lang thin.
• Very late-onset Friedreich’s ataxia (VLOFA): Hetah hian kum 40 an tlin hnuah a lan chhuah dan a intan thin.

Heng chi hnih, `(LOFA)` leh `(VLOFA)` te hi `(FA)` pangngai aiin a na deuh deuh a ni.

Hetiang natna lan chhuah dan hi engte nge ni?

Friedreich’s ataxia symptoms hi kum 5 leh 15 inkar atanga tan a ni tlangpui a, mahse, mi thenkhat chuan kum 2 atang pawhin an nei thei a, thenkhat chuan kum 50 atang pawhin an nei thei bawk.

A hmasa ber hmuh theih symptoms

Neurological symptoms lo lang hmasa ber chu ding harsa, kal harsatna, leh balance lama harsatna (Gait Ataxia an tih) te hi a ni. Hun a kal zel a, heng symptoms te hi a na zual sauh sauh a, symptom thar a lo lang thei bawk.

`(FA)` natna lan chhuahna nervous system nena inzawm lian ber berte chu:

• Muscle chak lohna.
• Balance leh coordination hloh (Ataxia).
• Touch sensation hloh (hei hi `(Peripheral Neuropathy)` an ti).
• Reflexes chak lohna (Hyporeflexia).

Heng features te hi hetah hian i tawng thei ang:

• Ding, kal leh tlan harsa.
• Chorea chu duh loh vanga taksa peng hrang hrang innghah leh khur hi a ni.
• Ke atanga intan a, kut leh pum chhungah a darh thin, hriatna hloh.

Mahse Doctor hnena an entir meuh chuan he `(FA)` chungchang hi an hre ta a ni.

Friedreich’s ataxia (FA) avanga harsatna dang lo awm thei te

FA vei zinga 75% velin lung natna an vei thei a ni. Chung zinga a tam ber chu:

Thinlung chunga nghawng a neih dan

• Thin lam natna (Cardiac Autonomic Neuropathy) a ni.
• Hypertrophic cardiomyopathy a awm a, a rilru a hah hle.
• Thinlung thawk mumal lo (Arrhythmia).

Tin, `(FA)` avanga thinlung lama harsatna dang lo awm thei te chu:

• Myocarditis natna (Myocarditis) a ni.
• Lung ruh (Myocardial Fibrosis) a hliam a awm.
• Thinlung lian zawk (Cardiomegaly).
• Congestive Heart Failure a awm thin.
• Lungphun chak tak (Tachycardia).
• Atrial fibrillation a awm thin.
• Heart Block a ni.

Zunthlum vei theihna a awm

FA hian i pancreas chhunga hormone insulin siamtu cell te chu a tichhe thei a ni. Thisen glucose level control nan insulin hi a pawimawh hle. Chuvangin, insulin a tlem chuan thisen sugar level a sang a, chu chuan hyperglycemia a thlen thin. Hei hian zunthlum a thlen thei a ni. FA vei zinga 30% velin zunthlum an vei thin.

Hei hi eng nge a chhan? Genetic influence a ni em?

Ni e, Friedreich-a ataxia hi genetic condition a ni vek. ``FXN'' tih gene pakhata inthlak danglamna, a nih loh leh mutation avanga lo awm a ni. He gene hian kan taksaa protein pawimawh tak, ``Frataxin'' siamna code a keng tel a ni.

Frataxin hi protein pakhat a ni a, mitochondria-ah a thawk a ni.

Frataxin hi kan cell-a chakna siamtu mitochondria -a awm protein a ni. Scientist-te chuan a hnathawh dan hi la hre chiang lo mah se, mitochondria hnathawh dan pangngai atan frataxin hi a pawimawh hle tih an hmuchhuak a ni. Frataxin (FA) siamtu gene mutation hian frataxin protein siam chhuah chu a titawp vek a ni.

Frataxin kan neih tlem hian kan taksa cell thenkhatte hian chakna an siam tha thei lo. Tin, toxic byproduct te pawh a pungkhawm tan bawk. Hei hi oxidative stress an ti a . Hei hian kan cell te a tichhe thin.

A hnuaia hmuna cell awmte hi `(FA)` hian a nghawng bik a ni:

• Peripheral Nerves te chu a awm a.
• Spinal Cord a ni.
• Thluak, a bik takin cerebellum.
• Heart muscle a ni.

Hei hi Autosomal Recessive Inheritance Pattern a ni a, hei hi a hlawhtling hle.

Friedreich’s ataxia hi (FXN) gene mutated copy pahnih, i nu leh pa hnen atanga i rochun chauhvin a awm thin. Doctor te chuan hei hi autosomal recessive inheritance pattern an ti a .

He natna vei nu leh pa pahnih hian mutated gene copy khat an nei tlangpui (chu chu carrier an ni tihna a ni ). Mahse a tlangpuiin symptom an lantir lo. Nu leh pa pahnih hi carrier an nih chuan, fa an neih hunah:

• Naupang hian `(FA)` (mutant gene pahnih hi rochun a nih chuan) a neih theihna chance 25% a awm.
• Naupang chu carrier (mutated gene pakhat rochun a nih chuan) a nih theihna chance 50% a awm.
• Naupang hi mutated genes rochun lovin a hrisel theihna chance 25% a awm.

Engtin nge hetiang chiah hian i diagnose? (Diagnosis) tih a ni.

A hmasain i fa doctor chuan symptoms leh family medical history a zawt ang. Tichuan physical exam kimchang leh neurological exam an nei ang.

A dawtah chuan doctor chuan test hrang hrang engemaw zat a rawt mai thei.Genetic testing hi Friedreich-a ataxia finfiah theihna tur test ber a ni. Chu bakah, a hnuaia test te hi natna hriatchhuahna atana pui tur leh/ emaw taksa chhunga hmun hrang hrang (FA) in a nghawng theih dan enfiah nan tih theih a ni bawk:

• MRI emaw CT scan: Hengte hian i thluak leh ruhro thlalak a la thei. Chûngte chuan i doctor chu neurological condition dangte a paih chhuah theih nân a ṭanpui thei a ni.
• Electromyogram (EMG) leh Nerve Conduction Studies: Heng test te hian i taksa ruh leh nerve te hnathawh dan a zirchiang thin.
• Electrocardiogram (ECG/EKG): Hei hian i thinlung electrical activity, chu chu heartbeat pattern a entir a ni.
• Echocardiogram: Hei hian i thinlung chetna thlalak a pe a.
• Thisen test: Thisen test thenkhat chu thisen sugar level leh vitamin E level te enfiah nan tih theih a ni.

Friedreich-a ataxia (FA) hi eng enkawlna nge ni?

Hei hi chanchin lawmawm tak a ni tak zet! Kum 2023 khan US Food and Drug Administration (FDA) chuan Friedreich-a ataxia atana damdawi bik siam hmasak ber chu a pawm a ni. Omaveloxolone (SKYCLARYSTM) tih a ni. Kum 16 chunglam tan hman theih a ni. Zirna hrang hrangah he damdawi hian nerve function leh ``Ataxia'' dinhmun chu eng emaw chen a tichak thei tih hmuhchhuah a ni. He damdawi hian hun rei tak chhunga nghawng a neih dan tur zirchianna dang neih mek a ni.

Mahse, Omaveloxolone hi FA damdawi a ni lo. He damdawi bakah hian enkawlna tum ber chu FA symptoms leh complications control a, a tha thei ang bera nun puih hi a ni. Chutiang enkawlnaah chuan:

• Physical Therapy: Hun rei tak chhung taksa ruh hnathawhna vawng reng a, inremna, inthlauhna leh chakna tihchangtlun.
• Speech Therapy: Lei leh hmai ruhte zirtir thar lehin thusawi leh ei leh in tihchangtlun.
• Braces emaw, ruh nena inzawm harsatna, ke ruh tliak leh scoliosis te tan surgery emaw tih a ni.
• Lung lam natna i neih chuan damdawi ei la.
• Zunthlum i vei chuan damdawi ei la.
• Natna tihreh dan tur.
• Infection laka invenna emaw enkawl nan antibiotics.
• Kea kalna atana puitu hmanrua, entirnan pheikhawk bik, tiang, wheelchair.
• Heart transplant hi FA mild enkawlna a ni a, mahse cardiomyopathy langsar tak a awm chuan.

FA enkawl tur chuan doctor team multidisciplinary te puihna i mamawh fo ang. He team hian:

• Neurologist te an ni.
• Cardiologist te an ni.
• Medical leh Biochemical Geneticist te an ni.
• Endocrinologist te hi doctor, endocrine system lama tui tak an ni.
• Taksa lam thiamte.
