Overview
The diagnosis of AIS is mostly made post-natally. Studies have shown that the AIS may be identified prenatally by imaging techniques and comparative study such as such as preimplantation genetic screening, noninvasive prenatal screening and ultrasonography.
Screening
- The diagnosis of AIS is mostly made postnatally. But, in a study which diagnosed mid-second trimester fetus with thick nuchal translucency (NT) / nuchal fold (NF) and short limbs was likely to be AIS. Hence, appearance of fetal sex on ultrasound should be compared with genetic sex. [1]
- With increased use, discordance among prenatal testing modalities such as preimplantation genetic screening, noninvasive prenatal screening and ultrasonography will become more common requiring expert navigation to identify true pathology. [2]
- In prepubertal girls with inguinal swellings, screening for CAIS should be considered. [3]
