hearing loss (hl) is the most frequent sensory defect present in 1 of every 500 newborns. in developed countries, at least 50% of cases are caused genetic factors, most often resulting in nonsyndromic hl (70%), which is usually autosomal recessive (80%). to date, fifty genes associated with autosomal recessive non-syndromic hearing loss (arnshl) have been reported.  the aim of this study was to...

background: phenylketonuria (pku) is an autosomal recessive disease of phenylalanine metabolism that brings deficiency of the enzyme phenylalanine hydroxylase (pah). early diagnosis is very important to prevent complications. this study was designed to describe characteristics of patients with phenylketonuria in mazandaran province in northern iran. methods: we studied 24 cases suffering from p...

Congenital cutis laxa is an exceptional condition. No large scale pedigree has been reported from Iran. We report a family with 106 members with two members affected with cutis laxa. Our cases were two patients (male and female) with pre- and postnatal growth retardation, cutis laxa, characteristic facies and other manifestations which proved that they were affected with cutis laxa. Their ...
