Clinical Terms in This Code Range

Definitions from the National Library of Medicine for conditions coded in the Q87 range.

Alport Syndrome

A genetic syndrome usually inherited as an X-link trait. It is caused by abnormalities in the COL4A5 gene. It affects males more often than females and is characterized by hematuria, progressive renal insufficiency, hearing loss, and ocular abnormalities.

Bardet-Biedl Syndrome

An autosomal recessive disorder characterized by RETINITIS PIGMENTOSA; POLYDACTYLY; OBESITY; MENTAL RETARDATION; hypogenitalism; renal dysplasia; and short stature. This syndrome has been distinguished as a separate entity from LAURENCE-MOON SYNDROME. (From J Med Genet 1997 Feb;34(2):92-8)

Beckwith-Wiedemann Syndrome

A syndrome of multiple defects characterized primarily by umbilical hernia (HERNIA, UMBILICAL); MACROGLOSSIA; and GIGANTISM; and secondarily by visceromegaly; HYPOGLYCEMIA; and ear abnormalities.

Birt-Hogg-Dube Syndrome

Autosomal dominant neoplastic syndrome characterised by genodermatosis, lung cysts, spontaneous and recurrent PNEUMOTHORAX; and RENAL CANCER. It is associated with mutations in the folliculin protein gene (FLCN protein).

Cockayne Syndrome

A syndrome characterized by multiple system abnormalities including DWARFISM; PHOTOSENSITIVITY DISORDERS; PREMATURE AGING; and HEARING LOSS. It is caused by mutations of a number of autosomal recessive genes encoding proteins that involve transcriptional-coupled DNA REPAIR processes. Cockayne syndrome is classified by the severity and age of onset. Type I (classical; CSA) is early childhood onset in the second year of life; type II (congenital; CSB) is early onset at birth with severe symptoms; type III (xeroderma pigmentosum; XP) is late childhood onset with mild symptoms.

De Lange Syndrome

A syndrome characterized by growth retardation, severe MENTAL RETARDATION, short stature, a low-pitched growling cry, brachycephaly, low-set ears, webbed neck, carp mouth, depressed nasal bridge, bushy eyebrows meeting at the midline, hirsutism, and malformations of the hands. The condition may occur sporadically or be associated with an autosomal dominant pattern of inheritance or duplication of the long arm of chromosome 3. (Menkes, Textbook of Child Neurology, 5th ed, p231)

Fraser Syndrome

Rare autosomal recessive congenital malformation syndrome characterized by cryptophthalmos, SYNDACTYLY and UROGENITAL ABNORMALITIES. Other anomalies of bone, ear, lung, and nose are common. Mutations on FRAS1 and FREM2 are associated with the syndrome.

Goldenhar Syndrome

Mandibulofacial dysostosis with congenital eyelid dermoids.

Kleefstra Syndrome

A condition caused by mutation or deletion of the EHMT1 gene, encoding histone-lysine N-methyltransferase EHMT1. It is characterized by severe intellectual disability, hypotonia, cardiac defects, and characteristic facial features.

Klippel-Trenaunay-Weber Syndrome

A congenital disorder that is characterized by a triad of capillary malformations (HEMANGIOMA), venous malformations (ARTERIOVENOUS FISTULA), and soft tissue or bony hypertrophy of the limb. This syndrome is caused by mutations in the VG5Q gene which encodes a strong angiogenesis stimulator.

Laurence-Moon Syndrome

An autosomal recessive condition characterized by hypogonadism; spinocerebellar degeneration; MENTAL RETARDATION; RETINITIS PIGMENTOSA; and OBESITY. This syndrome was previously referred to as Laurence-Moon-Biedl syndrome until BARDET-BIEDL SYNDROME was identified as a distinct entity. (From N Engl J Med. 1989 Oct 12;321(15):1002-9)

Loeys-Dietz Syndrome

An autosomal dominant aneurysm with multisystem abnormalities caused by increased TGF-BETA signaling due to mutations in type I or II of TGF-BETA RECEPTOR. Additional craniofacial features include CLEFT PALATE; CRANIOSYNOSTOSIS; HYPERTELORISM; or bifid uvula. Phenotypes closely resemble MARFAN SYNDROME; Marfanoid craniosynostosis syndrome (Shprintzen-Goldberg syndrome); and EHLERS-DANLOS SYNDROME.

Marfan Syndrome

An autosomal dominant disorder of CONNECTIVE TISSUE with abnormal features in the heart, the eye, and the skeleton. Cardiovascular manifestations include MITRAL VALVE PROLAPSE; AORTIC ANEURYSM; and AORTIC DISSECTION. Other features include lens displacement (ectopia lentis), disproportioned long limbs and enlarged DURA MATER (dural ectasia). Marfan syndrome (type 1) is associated with mutations in the gene encoding FIBRILLIN-1 (FBN1), a major element of extracellular microfibrils of connective tissue. Mutations in the gene encoding TYPE II TGF-BETA RECEPTOR (TGFBR2) are associated with Marfan syndrome type 2.

Nail-Patella Syndrome

A syndrome of multiple abnormalities characterized by the absence or hypoplasia of the PATELLA and congenital nail dystrophy. It is a genetically determined autosomal dominant trait.

Noonan Syndrome

A genetically heterogeneous, multifaceted disorder characterized by short stature, webbed neck, ptosis, skeletal malformations, hypertelorism, hormonal imbalance, CRYPTORCHIDISM, multiple cardiac abnormalities (most commonly including PULMONARY VALVE STENOSIS), and some degree of INTELLECTUAL DISABILITY. The phenotype bears similarities to that of TURNER SYNDROME that occurs only in females and has its basis in a 45, X karyotype abnormality. Noonan syndrome occurs in both males and females with a normal karyotype (46,XX and 46,XY). Mutations in a several genes (PTPN11, KRAS, SOS1, NF1 and RAF1) have been associated the NS phenotype. Mutations in PTPN11 are the most common. LEOPARD SYNDROME, a disorder that has clinical features overlapping those of Noonan Syndrome, is also due to mutations in PTPN11. In addition, there is overlap with the syndrome called neurofibromatosis-Noonan syndrome due to mutations in NF1.

Prader-Willi Syndrome

An autosomal dominant disorder caused by deletion of the proximal long arm of the paternal chromosome 15 (15q11-q13) or by inheritance of both of the pair of chromosomes 15 from the mother (UNIPARENTAL DISOMY) which are imprinted (GENETIC IMPRINTING) and hence silenced. Clinical manifestations include MENTAL RETARDATION; MUSCULAR HYPOTONIA; HYPERPHAGIA; OBESITY; short stature; HYPOGONADISM; STRABISMUS; and HYPERSOMNOLENCE. (Menkes, Textbook of Child Neurology, 5th ed, p229)

Rubinstein-Taybi Syndrome

A chromosomal disorder characterized by MENTAL RETARDATION, broad thumbs, webbing of fingers and toes, beaked nose, short upper lip, pouting lower lip, agenesis of corpus callosum, large foramen magnum, keloid formation, pulmonary stenosis, vertebral anomalies, chest wall anomalies, sleep apnea, and megacolon. The disease has an autosomal dominant pattern of inheritance and is associated with deletions of the short arm of chromosome 16 (16p13.3).

Silver-Russell Syndrome

Genetically and clinically heterogeneous disorder characterized by low birth weight, postnatal growth retardation, facial dysmorphism, bilateral body asymmetry, and clinodactyly of the fifth fingers. Alterations in GENETIC IMPRINTING are involved. Hypomethylation of IGF2/H19 locus near an imprinting center region of chromosome 11p15 plays a role in a subset of Silver-Russell syndrome. Hypermethylation of the same chromosomal region, on the other hand, can cause BECKWITH-WIEDEMANN SYNDROME. Maternal UNIPARENTAL DISOMY for chromosome 7 is known to play a role in its etiology.

Sjogren-Larsson Syndrome

An autosomal recessive neurocutaneous disorder characterized by severe ichthyosis MENTAL RETARDATION; SPASTIC PARAPLEGIA; and congenital ICHTHYOSIS. It is caused by mutation of gene encoding microsomal fatty ALDEHYDE DEHYDROGENASE leading to defect in fatty alcohol metabolism.

Sotos Syndrome

Congenital or postnatal overgrowth syndrome most often in height and occipitofrontal circumference with variable delayed motor and cognitive development. Other associated features include advanced bone age, seizures, NEONATAL JAUNDICE; HYPOTONIA; and SCOLIOSIS. It is also associated with increased risk of developing neoplasms in adulthood. Mutations in the NSD1 protein and its HAPLOINSUFFICIENCY are associated with the syndrome.

Weill-Marchesani Syndrome

Rare congenital disorder of connective tissue characterized by brachydactyly, joint stiffness, childhood onset of ocular abnormalities (e.g., microspherophakia, ECTOPIA LENTIS; GLAUCOMA), and proportionate short stature. Cardiovascular anomalies are occasionally seen.

Zellweger Syndrome

An autosomal recessive disorder due to defects in PEROXISOME biogenesis which involves more than 13 genes encoding peroxin proteins of the peroxisomal membrane and matrix. Zellweger syndrome is typically seen in the neonatal period with features such as dysmorphic skull; MUSCLE HYPOTONIA; SENSORINEURAL HEARING LOSS; visual compromise; SEIZURES; progressive degeneration of the KIDNEYS and the LIVER. Zellweger-like syndrome refers to phenotypes resembling the neonatal Zellweger syndrome but seen in children or adults with apparently intact peroxisome biogenesis.

About the Q87 Code Range

These conditions are present at birth and involve malformations affecting multiple body systems. The categories distinguish syndromes by their predominant features or by name.

Q87.0 focuses on facial appearance; Q87.1 focuses on short stature and separates Prader-Willi syndrome from other syndromes. Other subdivisions identify limb involvement, early overgrowth, or skeletal changes.

Q87.4 identifies Marfan syndrome, with further distinctions for cardiovascular, eye, and skeletal manifestations. Its cardiovascular codes distinguish aortic dilation from other manifestations. Q87.8 contains other specified syndromes, including several named conditions. Q87.A identifies Loeys-Dietz syndrome.

FY 2027 changes: The FY 2027 ICD-10-CM update, effective October 1, 2026, added Q87.A.
