Modes of inheritance:
Autosomal dominant inheritance
MedGen UID:
141047
Concept ID:
C0443147
Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in heterozygotes. In the context of medical genetics, an autosomal dominant disorder is caused when a single copy of the mutant allele is present. Males and females are affected equally, and can both transmit the disorder with a risk of 50% for each child of inheriting the mutant allele.

Disease characteristics

Excerpted from the GeneReview: Hand-Foot-Genital Syndrome
Hand-foot-genital syndrome (HFGS) is characterized by limb malformations and urogenital defects. Mild-to-severe bilateral shortening of the thumbs and great toes, caused primarily by shortening of the distal phalanx and/or the first metacarpal or metatarsal, is the most common limb malformation and results in impaired dexterity or apposition of the thumbs. Urogenital malformations include abnormalities of the ureters and urethra and various degrees of incomplete müllerian fusion in females, and hypospadias of variable severity with or without chordee in males. Vesicoureteral reflux, recurrent urinary tract infections, and chronic pyelonephritis may occur; fertility is normal. [from GeneReviews]

Additional descriptions

From OMIM
Hand-foot-genital syndrome (HFGS) is an autosomal dominant condition characterized by distal limb and distal genitourinary tract malformations. The most striking limb abnormality is first-digit hypoplasia, comprising short, proximally placed thumbs with hypoplastic thenar eminences and short, medially deviated halluces. There is also ulnar deviation of the second fingers, clinodactyly/brachydactyly of the fifth fingers, brachydactyly of the second to fifth toes, and delayed ossification, fusion, and shortening of the carpals and tarsals. These abnormalities appear to be fully penetrant, bilateral, and symmetrical, with little variation in severity. In contrast, genitourinary tract abnormalities are incompletely penetrant and variably severe, and include hypospadias in males, Mullerian duct fusion defects in females, vesicoureteric reflux, and pelviureteric junction obstruction (summary by Goodman et al., 2000).  http://www.omim.org/entry/140000
From MedlinePlus Genetics
Hand-foot-genital syndrome is a rare condition that affects the development of the hands and feet, the urinary tract, and the reproductive system. People with this condition have abnormally short thumbs and first (big) toes, small fifth fingers that curve inward (clinodactyly), and short feet. The bones in the wrists and ankles may be fused in people with this condition, or hardening of these bones may be delayed. The other bones in the arms and legs are normal.

Abnormalities of the genitals and urinary tract can vary among affected individuals. Many people with hand-foot-genital syndrome have defects in the ureters, which are tubes that carry urine from each kidney to the bladder, or in the urethra, which carries urine from the bladder to the outside of the body. Recurrent urinary tract infections and an inability to control the flow of urine (urinary incontinence) have been reported. About half of males with this disorder have the urethra opening on the underside of the penis (hypospadias).

People with hand-foot-genital syndrome are usually able to have children (fertile). In some affected females, problems in the early development of the uterus can later increase the risk of pregnancy loss, premature labor, and stillbirth.  https://medlineplus.gov/genetics/condition/hand-foot-genital-syndrome

Clinical features

From HPO
Vesicoureteral reflux
MedGen UID:
21852
Concept ID:
C0042580
Disease or Syndrome
Vesicoureteral reflux (VUR) is characterized by the reflux of urine from the bladder into the ureters and sometimes into the kidneys. It is a risk factor for urinary tract infections. Primary VUR results from a developmental defect of the ureterovesical junction (UVJ). In combination with intrarenal reflux, the resulting inflammatory reaction may result in renal injury or scarring, also called reflux nephropathy (RN). Extensive renal scarring impairs renal function and may predispose patients to hypertension, proteinuria, and renal insufficiency (summary by Lu et al., 2007). Genetic Heterogeneity of Vesicoureteral Reflux A locus designated VUR1 maps to chromosome 1p13. VUR2 (610878) is caused by mutation in the ROBO2 gene (602431) on chromosome 3p12; VUR3 (613674) is caused by mutation in the SOX17 gene (610928) on chromosome 8q11; VUR4 (614317) maps to chromosome 5; VUR5 (614318) maps to chromosome 13; VUR6 (614319) maps to chromosome 18; VUR7 (615390) maps to chromosome 12; and VUR8 (615963) is caused by mutation in the TNXB gene (600985) on chromosome 6p21. A possible X-linked form has been reported (VURX; 314550).
