Summaries for Khan-Khan-Katsanis Syndrome

OMIM® : 57 Khan-Khan-Katsanis syndrome (3KS) is an autosomal recessive neurodevelopmental disorder with variable involvement of the ocular, renal, skeletal, and sometimes cardiac systems. Affected individuals present at birth with multiple congenital anomalies, defects in urogenital and limb morphogenesis, poor overall growth with microcephaly, and global developmental delay (summary by Khan et al., 2019). (618460) (Updated 05-Mar-2021)

MalaCards based summary : Khan-Khan-Katsanis Syndrome, is also known as 3k syndrome. An important gene associated with Khan-Khan-Katsanis Syndrome is NCAPG2 (Non-SMC Condensin II Complex Subunit G2). Affiliated tissues include spinal cord and heart, and related phenotypes are failure to thrive and frontal bossing
