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 ...

: Wilson disease (WD) is an autosomal recessive with copper overload. Its clinical picture depends on specific tissue/system damage by the excess copper.

heredity hearing loss (hl) is the most prevalent sensory disorder and most cases are non-syndromic. eighty percent of non-syndromic sensorineural deaf patients show an autosomal recessive pattern of inheritance. to date, 47 genes and 98 loci have been reported for this mode of inheritance. previous studies in our center showed the high prevalence of dfnb3 among iranian deaf families. pjvk (dfnb...

this study aimed to investigate the contribution of four common dfnb (“dfn” for deafness and “b” for autosomal resessive locus) loci and gjb2 gene mutations (exon 2) in hearing impairment in individuals living in markazi and qom provinces of iran. forty consanguineous iranian families with at least three affected individuals in family or pedigree who suffer from an autosomal recessive non-syndr...

idiopathic hypogonadotropic hypogonadism (ihh) is a condition caused by low doses of hypothalamic gonadotropin-releasing hormone (gnrh) leading to absence or incomplete sexual maturation. one of the disorders leading to ihh is kallmann syndrome which is characterized by gnrh deficiency with anosmia or hyposmia. this disorder generally occurs as a hereditary syndrome with x-linked recessive inhe...

We devised a novel procedure to identify human cancer genes acting in a recessive manner. Our strategy was to combine the contributions of the different types of genetic alterations to loss of function: amino-acid substitutions, frame-shifts, gene deletions. We studied over 20,000 genes in 3 Gigabases of coding sequences and 700 array comparative genomic hybridizations. Recessive genes were sco...

PURPOSE To predict the progression to legal blindness in patients with isolated inherited retinitis pigmentosa. METHODS This retrospective study evaluated patients with isolated inherited retinitis pigmentosa for age at onset, duration of the disease, and best-corrected visual acuity in an Asian Indian cohort. The Mann–Whitney U test was used to analyze the variables. RESULTS Of 134 patient...
