The syndrome gets its name from the characteristic cry of affected infants, which is similar to that of a meowing kitten,<unk> e to problems with the larynx and nervous system. About one third of children lose the cry by age of 2 years. Other symptoms of<unk>  may include: * feeding problems because of difficulty in swallowing and sucking; * mutism; * low birth weight and poor growth; * severe cognitive, speech and motor disabilities; * behavioural problems such as hyperactivity, aggression, outbursts and repetitive movements; * unusual facial features, which may change over time; * excessive drooling; * small head (microcephaly) and jaw (micrognathism); * widely-spaced eyes (hypertelorism); * skin tags in front of eyes. Other common findings include hypotonia, a round face with full cheeks, epicanthal folds, down-slanting palpebral fissures (eyelids), strabismus, flat nasal bridge, down-turned mouth, low-set ears, short fingers, single palmar creases and cardiac defects (e.g., ventricular septal defect VSD, atrial septal defect ASD, patent<unk> ctus arteriosus PDA, tetralogy of Fallot). Infertility is not associated with<unk> <unk> <unk> . It has also been observed that people with the condition have difficulties communicating. While levels of proficiency can range from a few words to short sentences, it is often recommended by medical professionals for the child to undergo some sort of speech therapy/aid with the help of a professional. Less frequently encountered findings include cleft lip and palate, preauricular tags and fistulas, thymic dysplasia, intestinal malrotation, megacolon, inguinal hernia, dislocated hips, cryptorchidism, hypospadias, rare renal malformations (e.g., horseshoe kidneys, renal ectopia or agenesis, hydronephrosis), clinodactyly of the fifth fingers, talipes equinovarus, pes planus, syndactyly of the second and third fingers and toes, oligosyndactyly and hyper extensible joints. The syndrome may also include various dermatoglyphics, including transverse flexion creases, distal axial triradius, increased whorls and arches on digits and a single palmar crease. Late childhood and adolescence findings include significant intellectual disability, microcephaly, coarsening of facial features, prominent supraorbital ridges, deep-set eyes, hypoplastic nasal bridge, severe malocclusion and scoliosis. Affected females reach puberty, develop secondary sex characteristics and menstruate at the usual time. The genital tract is usually normal in females, except for a report of a bicornuate uterus. In males, testes are often small, but spermatogenesis is thought to be normal. Exceptionally, some with<unk> <unk> <unk>  are very high-functioning and do not seem very different from developmentally typical individuals, with mostly the exception of mild learning difficulties, and do not have speech difficulties, although they may have milder facial features and a high-pitched voice<unk> e to their condition.
