Publication Metadata only Clinical spectrum of cubulin mutations(2022-11-01) ALPAY, HARİKA; DEMİRCİ BODUR, ECE; ALAVANDA, CEREN; YILDIZ, NURDAN; ATA, PINAR; GÖKCE, İBRAHİM; Cicek N., ALPAY H., Guven S., Turkkan O.

Materials and Methods: Biochemical, clinical, and imaging findings were collected at presentation and the last clinic visit, and results of the genetic analysis were recorded. Results: Our study included 9 patients (3 female, 33%). The median age at diagnosis was 3 months, and the median follow-up period was 111 months. Height standard deviation scores were less than −2 in 4 (44%) patients at presentation and in 3 (33%) at the last clinic visit. The median estimated glomerular filtration rate was 98 mL/min/1.73 m2 at presentation and 126 mL/min/1.73 m2 at the last clinic visit. We have found 8 different types of mutations of 2 genes, including 6 in the ATP6V0A4 gene, 2 in the SLCA4A1 gene, and 2 of them were novel. At the time of presentation, nephrocalcinosis and hypercalciuria were present in all our patients, but at the last visit, only 1 patient had hypercalciuria. Sensorineural hearing loss was found in 4 of our patients with a mutation in the ATP6V0A4 gene. Serum ammonia levels were found to be high in 3 patients with mutations in the ATP6V0A4 gene. Conclusion: Adequate metabolic control is essential for optimal growth and preserved kidney function in distal kidney tubular acidosis patients. Distal kidney tubular acidosis may be associated with hyperammonemia. We recommend keeping potassium levels at high-normal levels to reduce ammonia levels, especially in the absence of acidosis.Publication Open Access First patient diagnosed as feingold syndrome type 2 with alport syndrome and review of the current literature(2022-12-01) ARMAN, AHMET; ATA, PINAR; SÖYLEMEZ, MEHMET ALİ; Demir S., SÖYLEMEZ M. A., ARMAN A., ATA P.Introduction: Feingold syndrome type 2 (FGLDS2) is an ultra-rare genetic disorder characterized by short stature, microcephaly, digital abnormalities, and intellectual disability. Until now, 22 patients have been reported in the literature. FGLDS2 is caused by a germline heterozygous deletion of 13q resulting in haploinsufficiency of the MIR17HG gene. Case report: In the present study, we evaluated clinical, radiological, and genetic analyses of a 10-year-old Turkish-origin girl with short stature, brachydactyly, intellectual disability, hematuria, and proteinuria. Conclusion/Discussion: In the array-CGH analysis, a 15.7-Mb deletion, arr[hg19] 13q22q31.3(78,241,132_93,967,288)x1, was detected, and this alteration was evaluated to be pathogenic. The deletion of this region covering the MIR17HG gene is a potential cause of FGLDS2. Also, at her clinical exome sequencing study, a heterozygous c.2023G>A p.(Gly675Ser) variation was detected in the COL4A5 gene (NM_000495.4) that was likely pathogenic in up-to-date databases. As a result, we report on a patient who has FGLDS2 and Alport syndrome. This is the first report of a Turkish-origin FGLDS2 patient. Reporting new cases expands the range of phenotypes, plays a crucial role in understanding the FGLDS2 pathogenesis, and is important in terms of screening at-risk family members for giving appropriate genetic counseling and preimplantation genetic diagnosis opportunities.Publication Metadata only Genetıc tests ın non-neurogenıc neurogenıc bladder: two sıblıngs wıth ochoa syndrome(2022-11-01) GÖKCE, İBRAHİM; ALAVANDA, CEREN; ŞEKERCİ, ÇAĞRI AKIN; DEMİRCİ BODUR, ECE; YILDIZ, NURDAN; YÜCEL, SELÇUK; ATA, PINAR; ALPAY, HARİKA; Pul S., GÖKCE İ., ALAVANDA C., ŞEKERCİ Ç.
