Genes affected

PRODH (HGNC:9453): (proline dehydrogenase 1) This gene encodes a mitochondrial protein that catalyzes the first step in proline degradation. Mutations in this gene are associated with hyperprolinemia type 1 and susceptibility to schizophrenia 4 (SCZD4). This gene is located on chromosome 22q11.21, a region which has also been associated with the contiguous gene deletion syndromes, DiGeorge and CATCH22. Alternatively spliced transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Aug 2010]

ACMG classification

Verdict is Likely_benign. Variant got -6 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.89).
• BP6: Variant 22-18922966-C-T is Benign according to our data. Variant chr22-18922966-C-T is described in ClinVar as [Benign]. Clinvar id is 1247033.Status of the report is criteria_provided_single_submitter, 1 stars.
