Summaries for Meier-Gorlin Syndrome 6

UniProtKB/Swiss-Prot : 75 Meier-Gorlin syndrome 6: A form of Meier-Gorlin syndrome, a syndrome characterized by bilateral microtia, aplasia/hypoplasia of the patellae, and severe intrauterine and postnatal growth retardation with short stature and poor weight gain. Additional clinical findings include anomalies of cranial sutures, microcephaly, apparently low-set and simple ears, microstomia, full lips, highly arched or cleft palate, micrognathia, genitourinary tract anomalies, and various skeletal anomalies. While almost all cases have primordial dwarfism with substantial prenatal and postnatal growth retardation, not all cases have microcephaly, and microtia and absent/hypoplastic patella are absent in some. Despite the presence of microcephaly, intellect is usually normal.

MalaCards based summary : Meier-Gorlin Syndrome 6, is also known as mgors6. An important gene associated with Meier-Gorlin Syndrome 6 is GMNN (Geminin, DNA Replication Inhibitor). Affiliated tissues include bone, and related phenotypes are frontal bossing and intellectual disability
