Periodontal Destruction

This paper aims to highlight the detrimental periodontal condition in patients with Papillon-Lefèvre syndrome (PLS) and the pivotal role of a Periodontist in the diagnosis of the condition. PLS is also known as palmo-plantar keratosis (PPK) with an unusual periodontal status. Uncontrolled early-onset periodontitis, which affects both primary and permanent dentitions alike, is a hallmark of the syndrome. PLS patients’ exhibit defected neutrophil chemotactic function due to substandard activity of Cathepsin C (CTSC) gene. The result is the failure of elimination of periodontal pathogens that leads to severe periodontal destruction. We reported a case of an 11 years old Pakistani girl affected with PLS whose parents are consanguineously married. Since PLS is a rare autosomal recessive disorder and multiple consanguinity in a family, increases the risk of the occurrence of the syndrome in the off springs, the case report also highlights the importance of pre-marital genetic mapping and conception counseling for the families.

Palmoplantar Hyperkeratosis

Papillon-Lefevre syndrome (PLS) is a rare autosomal recessive heterogeneous trait which is characterized by erythematous palmoplantar hyperkeratosis, early-onset periodontitis, and associated calcification of dura mater. The etiology of PLS is multifactorial with genetic, immunological, and microbial factors playing a role in etiopathogenesis. Recently identified genetic defect in PLS has been mapped to chromosome 11q14–q21, which involves mutations of cathepsin C. This paper presents a report of 2 cases of Papillon-lefevre syndrome in which diagnosis is based on clinical presentation and genetic mapping.

Синдром Барде-Бидля - аутосомно-рецессивное заболевание, характеризующееся ожирением, пигментной дегенерацией сетчатки, полидактилией, задержкой психоречевого развития и структурными повреждениями почек. В работе представлены результаты применения МПС-панели, включающей кодирующие последовательности и прилегающие интронные области 21 гена, ассоциированного с синдромом Барде-Бидля. Впервые была проведена молекулярно-генетическая диагностика в группе из сорока российских пациентов с синдромом Барде-Бидля из неродственных семей. В результате исследования удалось подтвердить диагноз молекулярно-генетическим методом у 40% пациентов (n=16). В генах BBS1, BBS7 и BBS10 встретились повторяющиеся варианты. Частота встречаемости патогенных и вероятно патогенных вариантов в генах BBS1 и BBS10 у российских пациентов соответствует зарубежным данным. Варианты в гене BBS7 встретились у пяти человек, у четырех из них был обнаружен патогенный вариант c.1967_1968delTAinsC, не встречающийся в других популяциях. Результаты, представленные в статье, показывают значительный вклад в заболеваемость синдромом Барде-Бидля в российской популяции патогенных вариантов в гене BBS7. Bardet-Biedl syndrome is an autosomal recessive disorder characterized by obesity, retinitis pigmentosa, polydactyly, development delay, and structural kidney defects. This study shows the results of using an MPS panel that includes coding sequences and intronic areas of 21 genes associated with Bardet-Biedl syndrome. For the first time molecular genetic testing has been provided for the group of 40 Russian patiens with Bardet-Biedl syndrome from unrelated families. As a result of the testing, diagnoses were confirmed for 40% of the patients (n=16). The genes BBS1, BBS7, BBS10 had recurrent variants. The frequency of pathogenic and likely pathogenic variants in the genes BBS1 and BBS10 among Russian patients matches the research data in other countries. Variants in the BBS7 gene were found for five people, four of them had a pathogenic variant c.1967_1968delTAinsC, which is not present among other populations. Results provided in this article show the significant role of pathogenic variants in the BBS7 gene in patients with Bardet-Biedl syndrome in Russian population.

Insight Into

Pycnodysostosis is an autosomal recessive disorder that manifests as osteosclerosis of the skeleton due to the defective osteoclasts mediated bone turnover. The diagnosis of this disorder is established on the basis of its characteristic features and must be differentially diagnosed with other bone disorders. Dental surgeons should be aware of the limitations and possible adverse oral complications such as osteomyelitis of bone in these patients. This will guide them in planning realistic treatment goals. This paper reports the clinical and radiographic features of pycnodysostosis with the great emphasis on its dentofacial characteristics. The aim of this case report is to give an insight into the etiology, pathogenesis, and differential diagnosis of this disorder and to prepare the dentists and maxillofacial surgeons to overcome the challenges in treating these patients.

Beta-ketothiolase deficiency is a rare autosomal recessive disorder of isoleucine and ketone body metabolism. This disorder is clinically characterized by ketoacidotic attacks. Ketoacidosis, vomiting, and dehydration, lethargy and coma may be seen during attacks. A 9-month-old girl was admitted to our hospital with acidosis and dehydration. The patient was lethargic. Ketoacidosis was suspected because of acetone odor on her breath. Her blood glucose level was 262 mg/dL and urine ketone was (++++). Branched chain amino acid levels were elevated in her blood sample. Organic acid analysis of urine revealed 2-methylacetoacetyl-CoA thiolase deficiency. This was reported because of rarity of the disease and we should consider it in the differential diagnosis of ketoacidotic episodes.

Background. Alpha II antiplasmin is a protein involved in the inhibition of fibrinolysis. A deficiency in this protein leads to increased hemorrhage. It is inherited in an autosomal recessive fashion.Case. 30-year-old Gravida 1, Para 0, presented for prenatal care with her first and subsequently her second pregnancy. Her medical history was significant for a known deficiency in alpha II antiplasmin. Her first and second pregnancies were complicated by nonobstetrical hemorrhage requiring transfusions and severe preeclampsia requiring preterm deliveries.Conclusion. Alpha II antiplasmin deficiency resulted in multiple episodes of nonobstetrical hemorrhages requiring transfusion and ultimately preterm deliveries due to severe preeclampsia. Both infants and mother had a good outcome. The presence of this disorder may require a multidisciplinary team approach involving obstetricians, pediatricians, and hematologists.Precis. Alpha II antiplasmin deficiency is a rare autosomal recessive disorder leading to increased fibrinolysis and hemorrhage. We present a case report of a pregnancy complicated by this disorder.

Translocation Pathway

The proton-coupled folate transporter (PCFT) mediates intestinal folate absorption, and loss-of-function mutations in this gene result in the autosomal recessive disorder hereditary folate malabsorption. The current study, focused on a structure-functional analysis of this transporter, identified Gly-189 and Gly-192 (a GxxG motif) located in the fifth transmembrane domain as residues that could not be replaced with alanine without a loss of function. In contrast, function was preserved when Gly-56 and Gly-59 (the other conservative GXXG motif in human PCFT) were replaced with alanine. Similarly, Gly-93 and Gly-97, which constitute the only conserved GXXXG dimerization motif in human PCFT, tolerated alanine substitution. To explore the role of this region in folate binding, the residues around Gly-189 and Gly-192 were analyzed by the substituted cysteine accessibility method. Both I188C and M193C mutants were functional and were inhibited by membrane-impermeable sulfhydryl-reactive reagents; this could be prevented with PCFT substrate, but the protection was sustained at 0°C only for the I188C mutant, consistent with localization of Ile-188 in the PCFT folate binding pocket. The functional role of residues around Gly-189 and Gly-192 is consistent with a molecular structural model in which these two residues along with Ieu-188 are accessible to the PCFT aqueous translocation pathway.
