HPO HP:0000158 Macroglossia "Increased length and width of the tongue." [PMID:19125428] Normal standards do not exist. Large size usually leads to protrusion of the tongue. This is an acknowledged bundled term, but due to its frequent usage and relative paucity of situations that would call for separate individual assessments of tongue dimensions, the bundled term is retained. Micrognathia may give the false appearance of a large tongue. HP:0003712, HP:0030809
HPO HP:0000280 Coarse facial features "Absence of fine and sharp appearance of brows, nose, lips, mouth, and chin, usually because of rounded and heavy features or thickened skin with or without thickening of subcutaneous and bony tissues." [PMID:19125436] HP:0001999
HPO HP:0000256 Macrocephaly "Occipitofrontal (head) circumference greater than 97th centile compared to appropriate, age matched, sex-matched normal standards. Alternatively, a apparently increased size of the cranium." [PMID:19125436] Macrocephaly can be due to hydrocephalus (increased CFSF), megalencephaly (increased brain volume) or thickening of the skull. Head circumference is measured from just above the glabella (the most prominent point on the frontal bone above the root of the nose) to the most posterior prominent point of the occipital bone using a tape measure. Some standard charts are organized by centiles [Hall et al. [2007]], others by standard deviations [Farkas, [1981]]. It is important to add an indication of how far above the normal standard the head circumference is if an accurate assessment of this can be made. Macrocephaly is an absolute term. The term relative macrocephaly can be used when the head size centile exceeds the centile for height, for example, head size at the 75th centile with height at the 5th centile for age and sex.

HPO HP:0002869 Flared iliac wing "Widening of the ilium ala, that is of the wing of the ilium, combined with external rotation, leading to a flared appearance of the iliac wing." [HPO:probinson, PMID:28744080] See Figure 4A of PMID:28744080. HP:0011867
HPO HP:0002245 Meckel diverticulum "Meckel's diverticulum is a congenital diverticulum located in the distal ileum." [HPO:probinson] HP:0001549
HPO HP:0000028 Cryptorchidism "Testis in inguinal canal. That is, absence of one or both testes from the scrotum owing to failure of the testis or testes to descend through the inguinal canal to the scrotum." [HPO:probinson, PMID:23650202] The gonad is mobile and can be retracted superiorly by the cremaster muscle reflex stimulated, for instance, by cold or touch. A retracted testis is not cryptorchidism. An abdominal testis cannot be distinguished by physical examination from an (Apparently) absent testis and requires radiological (or, rarely, surgical) procedures for assessment. HP:0000035
HPO HP:0002650 Scoliosis "The presence of an abnormal lateral curvature of the spine." [HPO:probinson] HP:0010674
HPO HP:0000158 Macroglossia "Increased length and width of the tongue." [PMID:19125428] Normal standards do not exist. Large size usually leads to protrusion of the tongue. This is an acknowledged bundled term, but due to its frequent usage and relative paucity of situations that would call for separate individual assessments of tongue dimensions, the bundled term is retained. Micrognathia may give the false appearance of a large tongue. HP:0003712, HP:0030809
HPO HP:0000384 Preauricular skin tag "A rudimentary tag of skin often containing ear tissue including a core of cartilage and located just anterior to the auricle (outer part of the ear)." [HPO:probinson] HP:0000383, HP:0010609
HPO HP:0006176 Two carpal ossification centers present at birth HP:0006257
HPO HP:0000776 Congenital diaphragmatic hernia "The presence of a hernia of the diaphragm present at birth." [HPO:probinson] Diaphragmatic hernia is the result of a developmental defect causing an abnormal opening in the diaphragm, through which abdominal organs (stomach, spleen, liver, and intestines) can protrude into the thoracic cavity. This usually causes respiratory distress in the newborn period. HP:0000775, HP:0100790
HPO HP:0005280 Depressed nasal bridge "Posterior positioning of the nasal root in relation to the overall facial profile for age." [PMID:19152422] The adjective "depressed" here does not indicate an active process but a status. A depressed nasal bridge can occur irrespective of the width of the nasal bridge, and the width should be assessed independently. In infancy, the nasal bridge is relatively more posterior than in the older person. The term depressed nasal bridge should only be used when the bridge is more posterior than is typical for age and ethnic background. HP:0000422
HPO HP:0000767 Pectus excavatum "A defect of the chest wall characterized by a depression of the sternum, giving the chest (\"pectus\") a caved-in (\"excavatum\") appearance." [HPO:probinson] HP:0000766
HPO HP:0001638 Cardiomyopathy "A myocardial disorder in which the heart muscle is structurally and functionally abnormal, in the absence of coronary artery disease, hypertension, valvular disease and congenital heart disease sufficient to cause the observed myocardial abnormality." [HPO:probinson, PMID:17916581] HP:0001637
HPO HP:0001540 Diastasis recti "A separation of the rectus abdominis muscle into right and left halves (which are normally joined at the midline at the linea alba)." [HPO:probinson] Diastasis recti looks like a ridge, which runs down the middle of the abdomen and increases with muscle straining. Diastasis recti is not uncommon in pregnant women and is common and normal in newborns. HP:0010991
HPO HP:0011675 Arrhythmia "Any cardiac rhythm other than the normal sinus rhythm. Such a rhythm may be either of sinus or ectopic origin and either regular or irregular. An arrhythmia may be due to a disturbance in impulse formation or conduction or both." [DDD:dbrown, PMID:19063792] HP:0030956
HPO HP:0000105 Enlarged kidney "An abnormal increase in the size of the kidney." [HPO:probinson] The main causes of large kidney are hydronephrosis, polycystic disease, renal cell carcinoma, nephroblastoma/Wilm's tumor (in children), and solitary cysts. If possible, a specific term should be used instead of this one. There are several ways of diagnosing enlarged kidney including intravenous urography. HP:0012210
HPO HP:0001638 Cardiomyopathy "A myocardial disorder in which the heart muscle is structurally and functionally abnormal, in the absence of coronary artery disease, hypertension, valvular disease and congenital heart disease sufficient to cause the observed myocardial abnormality." [HPO:probinson, PMID:17916581] HP:0001637
HPO HP:0001744 Splenomegaly "Abnormal increased size of the spleen." [HPO:probinson] HP:0003271, HP:0025408
HPO HP:0001162 Postaxial hand polydactyly "Supernumerary digits located at the ulnar side of the hand (that is, on the side with the fifth finger)." [HPO:sdoelken] HP:0001161, HP:0004207, HP:0100259
HPO HP:0002566 Intestinal malrotation "An abnormality of the intestinal rotation and fixation that normally occurs during the development of the gut. This can lead to volvulus, or twisting of the intestine that causes obstruction and necrosis." [HPO:probinson, PMID:12438031] HP:0002242
HPO HP:0000047 Hypospadias "Abnormal position of urethral meatus on the ventral penile shaft (underside) characterized by displacement of the urethral meatus from the tip of the glans penis to the ventral surface of the penis, scrotum, or perineum." [HPO:probinson, PMID:21968448] HP:0100627
HPO HP:0000238 Hydrocephalus "Hydrocephalus is an active distension of the ventricular system of the brain resulting from inadequate passage of CSF from its point of production within the cerebral ventricles to its point of absorption into the systemic circulation." [HPO:probinson, PMID:18211712, PMID:19410151] Hydrocephalus results from an imbalance between the rate of production of cerebrospinal fluid (CSF), mainly in the choroid plexus, and its reabsorption in the subarchnoid space over brain and spinal cord. HP:0002118, HP:0002921
HPO HP:0001643 Patent ductus arteriosus "In utero, the ductus arteriosus (DA) serves to divert ventricular output away from the lungs and toward the placenta by connecting the main pulmonary artery to the descending aorta. A patent ductus arteriosus (PDA) in the first 3 days of life is a physiologic shunt in healthy term and preterm newborn infants, and normally is substantially closed within about 24 hours after bith and completely closed after about three weeks. Failure of physiologcal closure is referred to a persistent or patent ductus arteriosus (PDA). Depending on the degree of left-to-right shunting, PDA can have clinical consequences." [HPO:probinson, PMID:20421261] HP:0011603
HPO HP:0001169 Broad palm "For children from birth to 4 years of age the palm width is more than 2 SD above the mean; for children from 4 to 16 years of age the palm width is above the 95th centile; or, the width of the palm appears disproportionately wide for the length." [HPO:probinson, PMID:19125433] Hand width is measured across the palm at the level of the MCPJ (radial aspect of the second MCPJ to the ulnar aspect of the fifth MCPJ) [Hall et al., 2007]. Caution is advised with the subjective assessment as short metacarpals can mimic a broad palm. In persons with polydactyly that includes a supernumerary metacarpal, that should be separately coded and the measurement technique from Hall et al, [2007] would need to be modified to account for the supernumerary digit (i.e., with postaxial polydactyly, measure to the sixth MCPJ).
