Cobalamin Metabolism Panel + Severe MTHFR Deficiency by Massively Parallel Sequencing
Test Information:	Confirmation of Clinical Diagnosis, Carrier Testing, Differential Diagnosis
Test Details
Test Code:	2120
Special Notes:	Sequence Analysis for the nineteen genes in Cobalamin Metabolism Panel + Severe MTHFR Deficiency by Massively Parallel Sequencing can be ordered separately: ABCD4 (#5130), ACSF3 (#2035), CBS (#3970), CD320 (#29125), GIF (#29120), HCFC1 (#29115), IVD (#3680), LMBRD1 (#2560), MCEE (#3395), MMAA (#3575), MMAB (#3580), MMACHC (#3440), MMADHC (#3885), MTHFR, MTR (#2050), MTRR (#2565), MUT (#3585), SUCLA2 (#3375), SUCLG1 (#3390), and TCN2 (#3965). For MTHFR Sequencing: This test is intended to detect variants associated with severe MTHFR deficiency. The c.665C>T (p.A222V) and c.1286A>C (p.E429A) variants in the MTHFR gene, if detected, are considered to be likely benign changes and may not be included in the report as testing for these two polymorphisms has limited clinical utility [Genet Med 2013:15(2):153-156]. An expanded report including the status of c.665C>T (p.A222V) and c.1286A>C (p.E429A) variants is available upon request.
