High Incidence of Genetic Defects in a Cohort of 24 Male Adolescents with Persistent Pubertal Gynecomastia

Paris Francoise , Gaspari Laura , MBou Felicien , Philibert Pascal , Lauber-Biason Anna , Sultan Charles

Background: Pubertal gynecomastia is a common condition appearing in up to 65% of adolescent boys. However, if male breast development is over B3–B4 and lasts more than 2–3 years, persistent pubertal gynecomastia (PPG) may be the sign of serious endocrine disease and the source of considerable psychological discomfort.Objective and hypotheses: We investigated a cohort of 24 adolescents with PPG followed at the Pediatric Endocrinogy Unit over a ...

Pubertal Virilization in Two Unrelated XY Teenagers with Female Phenotype due to NR5A1/SF-1 Gene Mutation

Philibert Pascal , Fenichel Patrick , Dewailly Didier , Audran Francoise , Fauconnet-Servant Nadege , Paris Francoise , Sultan Charles

Background: Pubertal virilization in a 46,XY DSD patient is generally due to partial androgen insensitivity, 5-alpha-reductase deficiency, or 17-ketoreductase deficiency. Recently, reports have identified virilization signs associated with NR5A1/SF-1 gene mutations.Cases presentation and method: We present two unrelated cases of pubertal virilization due to NR5A1/SF-1 gene mutation. Both were suspected to be primarily affected by 5-alph...

Partial Androgen Insensitivity: Syndrome or Symptoms?

Charles Sultan , Pascal Philibert , Nicolas Kalfa , Laurent Maimoun , Francoise Audran , Nadege Servant , Laura Gaspari , Francoise Paris

Background: Partial androgen insensitivity syndrome (PAIS) covers a large spectrum of phenotypes, with the common denominator being insufficient virilisation of the external genitalia in an XY child with normal testosterone (T) production. Genetic diagnosis of PAIS is based on the identification of an androgen receptor (AR) gene mutation.Aim: The aim of this work was to determine whether the PAIS-like phenotype is associated with other gene mutations.</p...

Familial Mutation of NR5A1/SF-1 Gene Associated with DSD and Spleen Agenesis: A New Syndrome?

Philibert Pascal , Poulat Francis , Audran Francoise , Cartigny Maryse , Paris Francoise , Sultan Charles , Manouvrier-Hanu Sylvie

Background: A recent report (JCI, 2014) described a new homozygous NR5A1/SF-1 mutation in a patient with XY DSD and spleen agenesis. To date, no other data have confirmed this association, raising the hypothesis of fortuity.Case presentation and method: We had the opportunity to study an adolescent girl referred for virilisation during puberty. She presented voice deepening and clitoral hypertrophy. Biological investigations showed high plasma testostero...

Prevalence of Partial Androgen Insensitivity Syndrome in 3 Cohorts of 46,XY Children Presenting with Isolated Hypospadias, Isolated Micropenis or Isolated Persistent Pubertal Gynecomastia

Francoise Paris , Pascal Philibert , Laura Gaspari , Francoise Audran , Nicolas Kalfa , Charles Sultan

Background: The clinical diagnosis of partial androgen insensitivity syndrome (PAIS) should be systematically considered for all 46,XY newborns/infants with undervirilisation contrasting with normal/elevated plasma testosterone levels. Confirmation of PAIS is based on the identification of an androgen receptor (AR) gene mutation.Aim: This work was undertaken to determine whether the minor forms of undervirilisation such as isolated hypospadias, isolated ...

Isolated Persistent Pubertal Gynecomastia in Three Adolescent Males as the Only Phenotypic Expression of PAIS with Androgen Receptor Gene Mutations

Philibert Pascal , M'Bou Felicien , Audran Francoise , Gaspari Laura , Paris Francoise , Sultan Charles

Background: Pubertal gynecomastia is observed in up to 65% of adolescent males. It is usually idiopathic and tends to regress within 1–2 years, although sometimes pubertal gynecomastia persists.Case presentation and methods: We investigated three adolescent males with isolated persistent pubertal gynecomastia: twin brothers and an unrelated adolescent boy. The twins (17 years) had normal male external genitalia. Biological testing showed normal test...

A New Mutation of MAMLD1 (CXorf6) Associated with NR5A1 (SF1) Variant in a Patient with 46,XY DSD

Background: The investigation of patients with 46,XY DSD is often difficult, with no definitive diagnosis in more than 50% of cases investigated. We describe a new mutation of MAMLD1 in a patient with 46,XY DSD who also showed an alteration in the NR5A1 gene.Case report: A 5-year-old boy was referred to our clinic for DSD. He was born to non-consanguineous parents and was diagnosed with ambiguous genitalia at birth but had not been previously investigate...

High Prevalence of SGA in Patients with Disorders of Sexual Development, Especially Idiopathic 46,XY DSD

Background: Disorders of sex development (DSD) are a group of rare conditions characterized by variable discordance between chromosomal, gonadal and phenotypic sex. An association between smallness-for-gestational age (SGA) and DSD is already recognised, but few studies have investigated this in detail.Aim of study: To evaluate the prevalence of SGA, among patients with DSD and to establish a correlation with the different types and causes of DSD.<p ...

Aetiology of 46,XY DSD in Algeria; Putative Modifier Role of pV89L Polymorphism in the SRD5A2 Gene in Androgen Receptor Mutation-Negative Subjects

Background: 46,XY DSD is a heterogeneous group of pathologies characterized by a wide spectrum of phenotypes and aetiologies. While advances in molecular genetics have permitted discovery of numerous genes implicated in testicular development, the diagnosis still remains uncertain for most patients with 46,XY DSD.Objective: To identify the aetiologies of 46,XY DSD in Algerian patients.Methods: We conducted a multicentre prospective...

Objective: Recent experimental data suggest that circulating serotonin interacts with bone metabolism, although this is less clear in humans. This study investigated whether serum serotonin interferes with bone metabolism in young women with anorexia nervosa (AN), a clinical model of energy deprivation.Methods: Serum serotonin, markers of bone turnover (osteocalcin (OC), procollagen type 1 N-terminal propeptide (PINP), type 1-C telopeptide breakdown prod...
