Entire Body System
- Short Stature
Affiliated tissues include kidney and bone, and related phenotypes are short stature and proteinuria [malacards.org]

Thus a diagnosis of short stature and refractory rickets due to Fanconi's syndrome secondary to Wilson's disease was made. [ijem.in]
Other causes of failure to thrive and short stature. Investigations The diagnosis is based on excessive loss of substances in the urine (eg, amino acids, glucose, phosphate, bicarbonate) in the absence of high plasma concentrations. [patient.info]
- Poor Growth
Clinical features include poor growth, fatigue, dehydration, polyuria, muscle weakness, and bone pain. Features on a basic blood panel includes hypokalemia, hypophosphatemia and metabolic acidosis. [radiopaedia.org]
Liver, Gall & Pancreas
- Hepatomegaly
Physical exam showed mild hepatomegaly and renal ultrasound showed resolution of calyceal calcifications. [bmcresnotes.biomedcentral.com]
Patients usually presents early in life with rickets and hepatomegaly. By two years of age enlarged kidneys are noticeable clinically. [omicsonline.org]
It is a rare inherited disorder of carbohydrate metabolism manifested by failure to thrive, hepatomegaly, severe hypophosphatemic rickets and proximal renal tubular dysfunction. [journalofpediatriccriticalcare.com]
Patients with SLC2A2 mutations may present either with isolated neonatal diabetes or with hepatomegaly and the renal Fanconi syndrome. [gt5.fantasticsams.biz]
Besides renal tubular dysfunction, other complications of cystinosis include eye disorders, Hepatomegaly, hypothyroidism, and other manifestations Symptoms in children are failure to thrive, growth retardation, and rickets. [slideshare.net]

Our patients (5 women and 2 men) developed renal tubular dysfunction, with hypophosphatemia, normoglycemic glycosuria, proteinuria, and decrease of creatinine clearance. [journals.lww.com]
[…] type 2 (proximal), hypophosphataemic rickets (children) or osteomalacia (adults), and renal glycosuria. [ 2, 3 ] Epidemiology The incidence of each cause of Fanconi's syndrome is different, although almost all of them are rather rare. [patient.info]
Proximal tubular dysfunction, resembling adult Fanconi's syndrome, was suggested by an increased urinary loss of phosphate and urate and glycosuria. [jamanetwork.com]
Glycosuria Glycosuria secondary to proximal tubule dysfunction is another of the cardinal features of Fanconi syndrome and results from impaired tubular reabsorption of glucose. It is often one of the first diagnostic clues. [abdominalkey.com]
Patients have polydipsia and polyuria with phosphaturia, glycosuria and aminoaciduria. They may develop hypophosphatemic rickets or osteomalacia, acidosis and a tendency toward dehydration. Some eventually develop renal insufficiency. [malacards.org]

- HLA-A2
They further noted that HLA-A2 and HLA-A24 haplotypes, mostly associated with TINU, have a high prevalence in Japan. Nonetheless, this association has not been confirmed [ 3 ]. [bmcnephrol.biomedcentral.com]
