Genes affected
TMEM165 (HGNC:30760): (transmembrane protein 165) This gene encodes a predicted transmembrane protein with a perinuclear Golgi-like distribution in fibroblasts. Mutations in this gene are associated with the autosomal recessive disorder congenital disorder of glycosylation, type IIk. Knockdown of this gene's expression causes decreased sialylation in HEK cells and suggests this gene plays a role in terminal Golgi glycosylation. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2012]
SRD5A3-AS1 (HGNC:44138): (SRD5A3 antisense RNA 1)

ACMG classification

Classification was made for transcript

Our verdict: Likely_benign. The variant received -1 ACMG points.

PP2
Missense variant in the gene, where a lot of missense mutations are associated with disease in ClinVar. The gene has 2 curated pathogenic missense variants (we use a threshold of 10). The gene has 0 curated benign missense variants. Gene score misZ: 1.3658 (below the threshold of 3.09). Trascript score misZ: 0.68834 (below the threshold of 3.09). GenCC associations: The gene is linked to TMEM165-congenital disorder of glycosylation.
BP4
Computational evidence support a benign effect (MetaRNN=0.09977156).
