In contrast to the two main nosological forms – Waardenburg syndrome types 1 and 3, caused by variants in this gene, the syndrome of craniofacial dysmorphias-deafness-anomalies of the upper limbs is not characterized by the presence of hair hypopigmentation and heterochromia of the iris, while congenital contractures of the wrist and interphalangeal joints of the hands. There is a description in the literature of three patients from the same family with a syndrome caused by the c.141C&gt;G(p.Asn47Lys) variant in the <italic>PAX3</italic> gene. Aim of the work is to present the clinical and genetic characteristics of the first Russian patient with the syndrome of craniofacial dysmorphia-deafness-anomalies of the upper extremities.</p><p>Molecular genetic analysis of a 1-year and 10-month-old proband with phenotypic signs of the syndrome of craniofacial dysmorphia-deafness-anomalies of the upper limbs was carried out by direct automatic Sanger sequencing of the entire coding sequence of the <italic>PAX3</italic> gene. Genotyping of parents was carried out by direct automatic sequencing according to Sanger. Sequencing was carried out on an ABIPrism3500хI instrument (Applied Biosystems) in accordance with the manufacturer’s protocol; primer sequences were selected according to the reference sequence of the target regions of the <italic>PAX3</italic> gene (NM_181459.4).</p><p>In Russian proband 1 year 10 months-old, the phenotypic characteristics of the syndrome of craniofacial dysmorphia-deafness-anomalies of the upper limbs did not differ from the description of sick family members presented in the literature. A molecular genetic study revealed a heterozygous variant c.141C&gt;G(p.Asn47Lys) in the <italic>PAX3</italic> gene in the presented patient.</p></abstract><trans-abstract xml:lang="ru"><p>Синдром черепно-лицевых дисморфий-глухоты-аномалий верхних конечностей – редкий аутосомно-доминантный синдром, обусловленный вариантами в гене <italic>PAX3</italic>. В отличие от 2 основных нозологических форм – синдрома Ваарденбурга 1-го и 3-го типов, обусловленных вариантами в данном гене, для синдрома черепно-лицевых дисморфий-глухоты-аномалий верхних конечностей не характерно наличие гипопигментации волос и гетерохромии радужки, при этом отмечаются врожденные контрактуры лучезапястных и межфаланговых суставов кистей.

Генотипирование родителей также осуществляли методом прямого автоматического секвенирования по Сэнгеру. Секвенирование проводили на приборе ABIPrism3500хI (Applied Biosystems) в соответствии с протоколом фирмы-производителя, последовательности праймеров были подобраны согласно референсной последовательности целевых участков гена <italic>PAX3</italic> (NM_181459.4).
