Intellectual Product
Source: Orphanet
A mode of inheritance that is observed for traits related to a gene encoded on one of the autosomes (i.e., the human chromosomes 1-22) in which a trait manifests in individuals with two pathogenic alleles, either homozygotes (two copies of the same mutant allele) or compound heterozygotes (whereby each copy of a gene has a distinct mutant allele).
Autosomal recessive inheritance (Orphanet)
 
Gene (location): SARDH (9q34.2)

Definition

Sarcosinemia is characterized by an increased concentration of sarcosine in plasma and an increased excretion of sarcosine in urine. Sarcosine (N-methylglycine) is enzymatically formed from dimethylglycine by dimethylglycine dehydrogenase (EC 1.5.99.2) and converted to glycine by sarcosine dehydrogenase (SARDH; 604455; EC 1.5.99.1). Some reports have associated sarcosinemia with mental retardation and neurologic problems, but the disorder is most likely benign and unrelated to significant clinical problems (summary by Scott, 2001). [from OMIM]
