We describe a 7-month-old male with atypical features of autosomal recessive distal renal tubular acidosis (dRTA) with sensorineural hearing loss. Uncharacteristically, he presented with mild acidosis, hypokalaemia and hypocalciuria as well as unilateral sensorineural hearing loss. Subsequent investigations led to the discovery of both hyperoxaluria and beta2-microglobulinuria, thereby expandin...
Two sibs are reported with upper limb defect, developmental delay, central hearing loss, unilateral poorly developed antihelix, and bilateral choroid coloboma. The inheritance is probably autosomal recessive.
Sensorineural non-syndromic hearing loss is the most common disorder which affects 1 in 500 newborns. Hearing loss is an extremely heterogeneous defect with more than 100 loci identified to date. According to the studies, mutations in GJB2 are estimated to be involved in 50- 80% of autosomal recessive non-syndromic hearing loss cases, but contribution of other loci in this disorder is yet ambig...
OBJECTIVE To investigate the molecular etiologic causes of sporadic nonsyndromic hearing loss in Chinese children. METHODS 179 sporadic nonsyndromic hearing loss children were subjected to microarray-based mutation detection for nine hot spot mutations in four of the most common deafness-related genes, including GJB2, SLC26A4, GJB3, and 12s rRNA. RESULTS The incidence of positive genetic er...
Introduction: Hearing loss is the most frequent sensory disorder occurs in 1/1000 newborns. About 50% of hearing loss cases are due to genetic causes. Mutation in MTRNR1(A1555G), MTTL1(A3243G) and MTTS1(A7445G) are known to be one of the important cause of nonsyndromic Sensorineural hearing loos in some populations. This study aims to demonstrate the frequency of three mitochondrial mutatio...
BACKGROUND Few studies have investigated ear involvement in nonsyndromic autosomal recessive congenital ichthyosis (ARCI). OBJECTIVES To assess the type and frequency of otologic manifestations of ARCI in patients under follow-up at the pediatric dermatology department of our hospital. MATERIALS AND METHODS We prospectively studied the presence of ear pain, ear itching, tinnitus, otitis, ce...
Postlingual progressive hearing loss, affecting primarily the high frequencies, is the clinical finding in most cases of autosomal dominant nonsyndromic hearing loss (ADNSHL). The molecular genetic etiology of ADNSHL is extremely heterogeneous. We applied whole-exome sequencing to reveal the genetic etiology of high-frequency hearing loss in a mid-sized Korean family without any prior linkage d...
Mutations of the unconventional myosins genes encoding myosin VI, myosin VIIA and myosin XV cause hearing loss and thus these motor proteins perform fundamental functions in the auditory system. A null mutation in myosin VI in the congenitally deaf Snell's waltzer mice (Myo6(sv)) results in fusion of stereocilia and subsequent progressive loss of hair cells, beginning soon after birth, thus rei...
