Introduction
Large gestational age (LGA) or macrosomia is a term used to describe a newborn with an excessive birth weight due to a range of known and unknown causes. There are many different definitions that have been used for to this term, generally a birth weight of 4000 to 4500 g (8 lb 13 oz to 9 lb 15 oz) or greater than 90% for gestational age after correcting for neonatal sex and ethnicity.
A recent study of USA data[1] suggests adverse perinatal outcomes of birthweight exceeded the 97th percentile. Their definition was a "birthweight greater than 4500 g in Whites, or 4300 g in Blacks and Hispanics regardless of gestational age is the optimal threshold to define macrosomia. A birthweight greater than the 97th percentile for a given gestational age, irrespective of race is also reasonable to define macrosomia."
- Duration of gestation - growth past the due date.
- maternal diabetes - presence of gestational diabetes; and class A, B, and C diabetes mellitus.
- Genetic Syndromes and Tumours - a range of overgrowth syndromes associated with developmental delay, tumors, and other anomalies with genetic causes and syndromes (Pallister-Killian, Beckwith-Wiedemann, Sotos, Perlman, and Simpson-Golabi-Behmel) rarely diagnosed prenatally.
Currently there is clinical research looking into the best mathematical formula, based upon ultrasound measurements, to estimate the possibility of macrosomia occurring.

Korea
Birth statistics of high birth weight infants (macrosomia) in Korea.[7]
We used 2 data sources, namely, the hospital units (1960's to 1990's) and Statistics Korea (1993 to 2010). The analyses include the incidence of high birth weight infants (HBWIs), birth weight distribution, sex ratio, and the relationship of HBWI to maternal age. The incidence of HBWIs for the past 50 years has been dropping in Korea. The older the mother, the higher was the risk of a HBWI and LBWI. We hope that these findings would be utilized as basic data that will aid those managing HBWIs.
Abnormalities
Beckwith-Wiedemann syndrome
Beckwith-Wiedemann syndrome (BWS) is an overgrowth disorder caused by either a mutation or deletion of imprinted genes within the chromosome 11p15.5 region. Infants show exomphalos, macroglossia, and gigantism and also have a predisposition to tumour development. Originally described by Beckwith and separately by Wiedemann in 1969.[8]

Pallister-Killian syndrome

Perlman syndrome
Perlman congenital overgrowth syndrome is an autosomal recessive syndrome similar to Beckwith-Wiedemann syndrome (BWS; OMIM 130650). Children are large at birth, hypotonic, show organomegaly, and have a high neonatal mortality.
- Facial abnormalities - inverted V-shaped upper lip, prominent forehead, deep-set eyes, broad and flat nasal bridge, and low-set ears.
- renal abnormalities - nephromegaly and hydronephrosis.
- neural abnormalities - neurodevelopmental delay.
Loss of function of DIS3 Like 3'-5' Exoribonuclease 2 (DIS3L2 exoribonuclease) generates a mouse model of this syndrome, following up-regulation of Insulin-like growth factor 2 (Igf2).[9] IGF2 has also been shown in other studies through microRNA miR-483-3p to contribute to macrosomia by regulating trophoblast proliferation.[10]
