SUPPLEMENTARY NOTES, FIGURES AND TABLES
Clinical features
Patients #1 and #2 are siblings from reportedly non-consanguineous, healthy parents, both
originating from a small village in the alpine region in North-Eastern Italy. Patient #1 is now a 37
year-old lady that was first examined at 5 years of age because of mild mental retardation and an
ataxic gait. These signs progressed over several years, and were accompanied by
hypodiadokokinesis, nystagmus on lateral gaze, diplopia, dysphagia, and dysphonia. At 24 years
she was unable to walk unaided because of ataxia and a mild right hemiparesis. She had rest and
intentional tremor and developed severe incoordination of both hands, with bilateral dysmetria, and
dysarthria, increased deep tendon reflexes and a bilateral Babinski sign. A series of brain MRIs
showed progression of necrotic lesions from an initial bilateral involvement of the caudate nuclei (at
18 years of age) to the present condition characterized by severe cerebellar atrophy with
leukodystrophic abnormalities, bilateral involvement of the inferior olives, substantia nigra, and
periaqueductal grey of the mesencephalon, external segment of the left putamen and both caudate
nuclei (Figure 1A). Although blood lactate was referred as normal, proton-specific mass
spectroscopy (1H-MRS) showed a lactate peak in both putamina. Axonal degeneration of the
second-motor neurons was documented by EMG. Because the brain MRI exams suggested a
metabolic, possibly mitochondrial, disease, we obtained a muscle biopsy from the left quadriceps at
30 years of age. Muscle histology and histochemistry, including reactions for COX and succinate
dehydrogenase (SDH, part of cII), were normal (Supplementary Figure 2), but analysis of the MRC
activities in muscle homogenate revealed the presence of an isolated, severe defect of cIII (Table 1).
Other MRC activities, several Krebs cycle enzymatic activities, as well as pyruvate dehydrogenase

(PDHC) activity were all normal. The patient is now wheelchair bound, with a stable IQ of 77,
severe dysarthria and upper limb ataxia.
Patient #2, the younger brother of patient #1, is now 26 yo. His disease onset was at 10 years with
mild gait ataxia and poor scholastic performance mainly due to difficulty in verbal and written
language skills. He then suffered of a rapid downhill course characterized by progressive
incoordination of the upper and lower limbs, dysarthria, dysphonia, severe cognitive regression,
bilateral hearing loss, spontaneous nystagmus, and dystonia of both hands and right foot. Weakness
of the ocular muscles ensued in the left eye, due to a pontine-mesencephalic lesion involving the
nuclei of the VI and IV left cranial nerves. The patient is now bedridden, in a fluctuating comatose
status, under permanent mechanical ventilation through tracheostomy, and fed by a percutaneous
endoscopic gastrostomy (PEG) tube. A muscle biopsy performed at age 20 years was
morphologically normal, but again revealed a severe isolated defect of cIII by biochemical assay
(Table 1).
Myoblasts obtained from the muscle biopsy of patient #2 showed an isolated, 50% reduction of cIII
activity, whereas skin fibroblasts from both patients were biochemically normal in standard
conditions. However, a partial cIII defect was detected when fibroblasts were forced to rely on
OXPHOS rather than glycolysis, by replacing glucose with galactose in the culturing medium
(Table 1). In addition, using a micro-scale oxygraphic method, the oxygen consumption in intact
fibroblasts from both patients #1 and #2, and myoblasts from patient #2, all cultured in either
glucose (Figure 1B of main text) or galactose (not shown) medium, was significantly decreased
compared to normal control fibroblasts, clearly indicating impairment of overall respiratory activity.
Patient #3, a young lady now 19 years old, is the only child from reportedly non-consanguineous
healthy parents, originating from the same area of Central Italy. She had a clinical course very
similar to that of patient #2, with onset at 5 years of an ataxic gait, severe regression of language
skills, and mental impairment characterized by lack of interest, and poor social interaction. The

disease progressed up to the present condition characterized by severe ataxia, scoliosis, dystonia of
the left foot and both hands, and cognitive impairment, worsened by a recent episode of
cardiorespiratory arrest due to prolonged central apnea, requiring heroic resuscitation in an ICU.
Lactate was slightly elevated in blood. She is now bedridden, in a fluctuating comatose status, under
permanently assisted ventilation and PEG feeding. Several brain MRIs performed over time
documented the development of necrotic lesions scattered from the medulla oblongata, including
both inferior olives, through the pons and cerebellum, and up to the mesencephalon, including
cerebral peduncles and periaqueductal grey matter. She later developed multiple bilateral lesions in
the thalami, cerebellar atrophy and severe axonal degeneration of motor peripheral nerves,
indicating second-motor neuron involvement (Supplementary Figure 1). A muscle biopsy was
morphologically normal but biochemical assay of MRC complexes showed marked isolated
reduction of cIII activity (Table 1).
Patient #4, born from reportedly non-consanguineous healthy parents from Southern Italy, had a
normal psychomotor development with no clinically relevant complaints until the age of 42 years,
when he was first examined for a subacute, rapidly progressive neurological syndrome
characterized by weakness of the four limbs with fasciculations, initially suggesting a motor-neuron
disease, followed by apraxia of gait and hand movements, dysarthria, bradykinesia, dystonia and
paraparesis. Lack of initiative and avoidance behavior rapidly ensued with marked slowness in
ideation, but relative conservation of cognition and critical judgment. A brain MRI showed diffuse
cortical atrophy and necrotic lesions in the right caudate nucleus and both putamina (Supplementary
Figure 1). In these regions a 1H-MRS revealed the presence of a lactate peak. A brain SPECT
showed reduced perfusion of the frontal and parietal lobes. Axonal degeneration of the peripheral
motor nerves was documented by EMG. Jacob-Creutzfeld and Wilson disease, chorea-
acanthocytosis, and several other neurodegenerative conditions were all excluded. A CT scan
showed marked muscle atrophy in the lower limbs and upper limb girdle, with fat substitution. A

muscle biopsy showed mild anisometry, mild lipid accumulation and a few scattered COX-negative
fibers (Supplementary Figure 2). The measurement of the MRC complex activities revealed
marked, isolated cIII deficiency (Table 1). The patient died at 45 years, two years after the disease
onset.

Analysis of the insertion of the PiggyBac element within the cg15173 gene (A) and transcript (B).

PCR amplification of the cg15173 gene from genomic DNA obtained from wild-type (WT) and
knock-out (KO) flies. Numbers refer to the amplicons reported in Supp Table 5. M: molecular
weight markers ΦX174 (HaeIII). Amplicons #4 and #5 are present only in the KO DNA, since they
contain the 5’ and 3’ insertion points of the PiggyBac element respectively, being obtained using
primer pairs corresponding to a region of the cg15173 gene and of the PiggyBac transposable
element. Amplicon #2 is present only in WT DNA, being obtained by a primer pair corresponding
to 5’ and 3’ regions of the cg15173 gene, flanking the transposable element, which is too big to
produce a detectable fragment from the KO DNA.

shown in A and indicate the absence of the normal transcript in the KO fly, which is replaced by an
aberrant transcript that includes the transposable element.

Electroretinogram in wild-type and dm.TTC19 KO adult aged flies
Electroretinograms recorded extracellularly from 27 day-old adult wild type (A) and dm.TTC19-KO
(B) flies, following white light stimulation. After the onset of a light stimulus, a brief ON transient
positive deflection of the trace, corresponding to lamina neurons activity, is followed by a negative
sustained deflection of the trace, determined by photoreceptor response. At the cessation of the light
stimulus, an OFF transient, expressed as a negative deflection, is followed by a slow recovery to the
pre-stimulus condition. The original responses (3s duration) have been magnified to show both ON
and OFF transients. In both wild-type (A) and dm.TTC19-KO (B) electroretinograms, ON and OFF
transients are equally present. In conclusion, the electroretinogram of the TTC19 KO individual is
comparable to that of the wild-type individual, indicating the integrity of the photoreceptive organ
in both animals.
