Do you know this syndrome? Dyspigmentation along the Blaschko lines caused by t...

Dyspigmentation along the Blaschko lines is strongly suggestive of a mosaic skin disorder. We report a 9-year-old male patient who presented with swirls and streaks of both hypo and hyperpigmentation involving the entire body. Additionally, he had hypertrichosis, musculoskeletal and minor neurodevelopment abnormalities but no intellectual disability. Cultured fibroblast displayed trisomy 7 mosaicism, which can ...

Copy number variants prioritization after array-CGH analysis - a cohort of 1000...

Array-based comparative genomic hybridization has been assumed to be the first genetic test offered to detect genomic imbalances in patients with unexplained intellectual disability with or without dysmorphisms, multiple congenital anomalies, learning difficulties and autism spectrum disorders. Our study contributes to the genotype/phenotype correlation with the delineation of laboratory criteria which help to ...

Phenotypic expression in hypertrophic cardiomyopathy and late gadolinium enhanc...

INTRODUCTION AND AIM: The prognostic value of late gadolinium enhancement (LGE) for risk stratification of hypertrophic cardiomyopathy (HCM) patients is the subject of disagreement. We set out to examine the association between clinical and morphological variables, risk factors for sudden cardiac death and LGE in HCM patients. METHODS: From a population of 78 patients with HCM, we studied 53 who underwent cardi...

Intellectual disability, unusual facial morphology and hand anomalies in sibs

Here we report on a Portuguese family with three sisters who shared moderate intellectual disability, unusual facial morphology (short palpebral fissures; broad nasal tip; thin upper and lower vermillion; broad and pointed chin) and hand anomalies in two of them (short left third and fifth right metacarpals in one case; marked syndactyly between the third and fourth fingers in another). One of the sisters had m...

Non-syndromic Sensorineural Prelingual Deafness: The Importance of Genetic Coun...

Recent advances in molecular genetics have allowed the determination of the genetic cause of some childhood non-syndromic deafness. In Portugal only a small proportion of families are referred to a clinical genetics service in order to clarify the etiology of the deafness and to provide genetic counseling. Consequently, there are no published studies of the prior beliefs of parents about the causes of hereditar...

Avaliação e Investigação Etiológica do Atraso do Desenvolvimento Psicomotor / D...

Developmental Delay (DD) and Intellectual Disability (ID), depending on the affected individual being under or above five years-old, result from environmental or genetic causes during the developmental period, that manifest as a subnormal functioning of intellectual abilities. In western countries there is a prevalence of about 3%, with a great impact in the individuals, their families, as well as in the societ...

A Síndrome de Smith-Lemli-Opitz: Características Fenotípicas e Genotípicas dos ...

A síndrome de Smith-Lemli-Opitz (SLOS) é uma síndrome polimalformativa de transmissão autossómica recessiva causada por um défice metabólico da biossíntese do colesterol, que se caracteriza por dismorfias craniofaciais, anomalias congénitas de vários órgãos (salientando-se as do esqueleto e do aparelho urogenital), restrição de crescimento intra-uterino (RCIU), alterações comportamentais e atraso mental. É caus...

Mutations in the MECP2 Gene Are Not a Major Cause of Rett Syndrome-Like or Rela...

Rett syndrome is a genetic neurodevelopmental disorder that affects mainly girls, but mutations in the causative MECP2 gene have also been identified in boys with classic Rett syndrome and Rett syndrome-like phenotypes. We have studied a group of 28 boys with a neurodevelopmental disorder, 13 of which with a Rett syndrome-like phenotype; the patients had diverse clinical presentations that included perturbation...
