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

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

PS1
Transcript NM_016335.6 (PRODH) is affected with MISSENSE_VARIANT having same AA change as one Pathogenic present in UniProt
BP4
Computational evidence support a benign effect (MetaRNN=0.012216002).
BS1
Variant frequency is greater than expected in population afr. gnomad4_exome allele frequency = 0.0125 (2640/211074) while in subpopulation AFR AF= 0.0384 (329/8564). AF 95% confidence interval is 0.035. There are 181 homozygotes in gnomad4_exome. There are 1348 alleles in male gnomad4_exome subpopulation. Median coverage is 0. This position pass quality control queck.
BS2
High Homozygotes in GnomAdExome4 at 181 AR gene
