Abstract
Background: Hereditary hypotrichosis simplex is a rare genetic hair disease that affects the scalp. Failure to grow normal hair in terms of length and density is the main complaint of patients. Diagnosis usually established by exclusion of other congenital hair and other ectodermal disorders. Till now, no satisfactory treatment was used for the condition.Report: A 14 year old patient with hypotrichosis simplex was treated with combined platelet rich plasma injection and topical minoxidil 2% with marked improvement.Conclusion: While no satisfactory treatment presents for this condition, the use of platelet rich plasma injection can add new hope for hypotrichosis simplex patients.

Short anagen hair syndrome: association with mono- and biallelic variants in WNT10A and a genetic overlap with male pattern hair loss. Br J Dermatol 2023; 189:741-749. [PMID: 37671665 DOI: 10.1093/bjd/ljad314] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/23/2023] [Revised: 08/08/2023] [Accepted: 08/23/2023] [Indexed: 09/07/2023]
Abstract
BACKGROUND Short anagen hair (SAH) is a rare paediatric hair disorder characterized by a short anagen phase, an inability to grow long scalp hair and a negative psychological impact. The genetic basis of SAH is currently unknown. OBJECTIVES To perform molecular genetic investigations in 48 individuals with a clinical phenotype suggestive of SAH to identify, if any, the genetic basis of this condition. METHODS Exome sequencing was performed in 27 patients diagnosed with SAH or with a complaint of short, nongrowing hair. The cohort was screened for variants with a minor allele frequency (MAF) < 5% in the general population and a Combined Annotation Dependent Depletion (CADD) score > 15, to identify genes whose variants were enriched in this cohort. Sanger sequencing was used for variant validation and screening of 21 additional individuals with the same clinical diagnosis and their relatives. Genetic association testing of SAH-related variants for male pattern hair loss (MPHL) was performed using UK Biobank data. RESULTS Analyses revealed that 20 individuals (42%) carried mono- or biallelic pathogenic variants in WNT10A. Rare WNT10A variants are associated with a phenotypic spectrum ranging from no clinical signs to severe ectodermal dysplasia. A significant association was found between WNT10A and SAH, and this was mostly observed in individuals with light-coloured hair and regression of the frontoparietal hairline. Notably, the most frequent variant in the cohort [c.682T>A;p.(Phe228Ile)] was in linkage disequilibrium with four common WNT10A variants, all of which have a known association with MPHL. Using UK Biobank data, our analyses showed that c.682T>A;p.(Phe228Ile) and one other variant identified in the SAH cohort are also associated with MPHL, and partially explain the known associations between WNT10A and MPHL. CONCLUSIONS Our results suggest that WNT10A is associated with SAH and that SAH has a genetic overlap with the common phenotype MPHL. The presumed shared biologic effect of WNT10A variants in SAH and MPHL is a shortening of the anagen phase. Other factors, such as modifier genes and sex, may also play a role in the clinical manifestation of hair phenotypes associated with the WNT10A locus.

Abstract
Loose anagen syndrome (LAS) and short anagen syndrome (SAS) are congenital hair disorders presenting with reduced hair length with or without hair thinning. We conducted a non-validated online questionnaire of self-identified familial participants in a Facebook support group to assess psychologic symptoms, including anxiety, depression, low self-esteem, sadness, insecurity, worry, frustration, and body dysmorphia, in patients and their caregivers. Of 163 total respondents, negative psychologic symptoms were reported in 44.2% (38/89) of LAS patients, 48.3% (43/89) of LAS caregivers, 56.8% (42/74) of SAS patients, and 47.2% (35/74) of SAS caregivers. Our data indicate that both LAS and SAS have strong psychologic, emotional, and social impacts on affected children and their caregivers.

Abstract
BACKGROUND The short anagen syndrome (SAS) is a rare idiopathic pediatric disorder characterized by the short duration of the anagen phase. SAS mainly affects Caucasian children. Parents complain of their child's inability to grow long hair. Topical minoxidil may be an effective treatment for SAS; however, a slow spontaneous improvement is typical. OBJECTIVE Our aim was to collect data on out cases of SAS and create an algorithm to facilitate diagnosis of SAS. METHODS A retrospective review of 25 patients with SAS was performed within the Dermatology Department of the University of Bologna. We collected data regarding symptoms, pull test, hair card test, trichoscopy, trichogram, treatments, including biotin and minoxidil, and clinical outcome. RESULTS Characteristic findings included parental reporting that the hair had not required a haircut, hair card test showing hairs with conical-shaped tips, and hair shafts of different diameters, with more 10%-20% of hair shafts less than 60 μm thick on trichoscopy. Trichogram revealed an increased percentage of telogen hair with normal hair shafts and tapering ends. The mean anagen-to-telogen ratio was 66:34 (normal ratio 90:10). CONCLUSION We developed an algorithm to facilitate the diagnosis of this rare hair disease using clinical examination and invasive and non-invasive testing to differentiate SAS from other forms of pediatric alopecia. In conclusion, the collected data of the therapy showed that biotin alone or in combination with topical minoxidil is an effective treatment for SAS.
