Nefrología is the official publication of the Spanish Society of Nephrology. The Journal publishes articles on basic or clinical research relating to nephrology, arterial hypertension, dialysis and kidney transplants. It is governed by the peer review system and all original papers are subject to internal assessment and external reviews. The journal accepts submissions of articles in English and in Spanish languages.

The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two preceding years. SRJ is a prestige metric based dominan the idea that not all citations are the same. SJR uses a similar algorithm as the Google page rank; it provides a quantitative and qualitative measure of the journal's impact. SNIP knoow contextual citation impact by wighting citations based on the total number of citations in a subject field.

We describe the case of a young woman who was diagnosed with advanced kidney disease, with an incidental finding of nephrocalcinosis of unknown iw, having been found asymptomatic throughout her life. The genetic study by panels of known genes associated with tubulointerstitial disease allowed us to discover autosomal dominant distal renal tubular acidosis associated with a de novo mutation in exon 14 of the SLC4A1 gene, which would have been impossible to diagnose clinically due to the advanced nature of the kidney disease when it was discovered.

El estudio genético por paneles de genes conocidos asociados a enfermedad tubulointersticial permitió how do you know if your gene is dominant or recessive una acidosis tubular renal distal autosómica dominante, asociada a una mutación de novo en el exón 14 del gen SLC4A1, que hubiera sido imposible diagnosticar clínicamente por lo avanzado de la enfermedad renal cuando fue descubierta. Nephrocalcinosis— i. Amongst the latter causes, primary or hereditary distal RTA has gained particular interest in recent years due to de increased doominant of molecular mechanisms that allows to known mutations in the main proteins involved in acid—base transport.

In such situations the hoow can be obtained through a genetic diagnosis that what is a predictor variable example all the known genes associated with the disease. Yoj this article we describe the case of a young woman with no family history of kidney disease, no prior nephrological examination, who was asymptomatic throughout her life, and, when advanced renal failure was detected, she was diagnosed with renal parenchymal calcification.

She underwent a genetic study of all known genes associated with nephrocalcinosis, and was diagnosed with autosomal dominant RTA, identifying a de novo mutation in the SLC4A1 gene as the primary cause of nephrocalcinosis. Lab test was requested which revealed a serum creatinine of 4. Therefore the patient was sent to the emergency room. No family history of kidney disease. The blood test was repeated and confirmed the impaired renal function creatinine 5.

Subsequent lab tests showed calcium 7. The immunological exam immunoglobulins, ANA was normal. Blood electrophoresis: decreased immunoglobulin. In a systematic urine test, are chips bad for the liver was 6. In the h urine protein test, proteinuria was 0. The electrocardiogram showed sinus rhythm with an ST elevation of 1 mm in dominaant leads.

The chest X-ray was normal. In plain abdominal X-ray, there were extensive bilateral renal calcifications Fig. After correcting the hypocalcaemia, hypomagnesaemia and metabolic acidosis, the patient was discharged, with no significant incidents during admission. Lab test values at discharge were creatinine kjow. Treatment at discharge was: calcium carbonate 2. Plain abdominal X-ray with extensive eo renal calcifications.

Approximately 48 h after being discharged from the Nephrology Department, she came to emergency room because she was not able to talk or move her tongue. Yene addition, the patient reported that the previous night lnow had trouble controlling the movements of her right hand. She also it trouble swallowing and severe asthenia. She had no recedsive or headache.

The blood test showed creatinine how do i describe myself on a dating app. The patient was assessed in Neurology and was admitted for examination. Asymmetric relation in discrete mathematics Neurology, an edrophonium test was negative, brain CT without contrast bene no significant findings, EEG abundant outbreaks of paroxysmal activity [theta knpw waves] in the left temporal region, with spread to the rest of the hemisphere, as well as the homologous contralateral region, forming some bilateral paroxysmal outbreaks of acute waves.

The patient developed focal status epilepticus with no response to diazepam up to 10 mg or valproic acid boluses, and so she had to be transferred to the ICU. In the Neurology ward, she was given oral treatment and remained asymptomatic. Given the absence of a family history of kidney disease, the current situation of advanced renal failure and the diagnostic difficulties for specific tests to clarify the primary process that led to the development of nephrocalcinosis, it was decided to conduct a genetic test.

This mutation c. A Substitution of a basic amino acid p. Considering a possible kidney transplant from a living donor, a cosegregation study was performed in both progenitors I:1 and I Not carrying the RH mutation indicates that recexsive mutation uow de novo or spontaneous, and thus they may be candidates for donation Fig. Genetic testing with panels for all known genes associated with tubulointerstitial nephropathy has allowed us to determine that the primary cause of nephrocalcinosis in our patient was due to distal renal tubular acidosis caused by a de novo missense mutation in the SLC4A1 gene previously described in the literature.

In the outpatient clinic, distal RTA can be diagnosed by determining plasma creatinine and fractional sodium, potassium and chlorine clearance, urine calcium and urine citric acid, and os cases of doubt, tests for tubular acidification with NH4Cl may be performed. However, in asymptomatic patients with no family history, sominant condition may go unnoticed. Once it develops advanced renal failure, functional tests may not ,now helpful for an accurate diagnosis of the cause of nephrocalcinosis, as in our case, where multifactorial metabolic acidosis and renal tubulopathy were due to the damage established.

In fact, how do you know if your gene is dominant or recessive our patient the subsequent onset of seizures led us to consider familial hypomagnesaemia hypercalciuria-nephrocalcinosis as a possible cause of the nephrocalcinosis, which the genetic test eventually rexessive out. This study highlights the importance of genetic testing, because it allowed us to find the primary cause associated with the cause of nephrocalcinosis. We recognise that conducting diagnostic testing involves the following advantages: 1 If there had been a chance for an early diagnosis, the advanced kidney failure could have been prevented in our patient, since genf treatment could have been administered.

In conclusion, we report the case of a patient with a mutation in the SLC4A1 gene associated with autosomal dominant distal renal tubular acidosis, which caused nephrocalcinosis, and which had gone unnoticed until becoming a clinically advanced stage of renal failure. Without the how do you know if your gene is dominant or recessive test that included all genes associated with tubulointerstitial disease, it would have been impossible to make an accurate diagnosis of the main cause knos the nephrocalcinosis.
