Variant summary

Our verdict is Uncertain significance. Variant got 0 ACMG points: 2P and 2B. PM2 BP4_Moderate

The NM_018198.4(DNAJC11):​c.1180G>T​(p.Val394Leu) variant causes a missense change. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 12/21 in silico tools predict a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar. Another variant affecting the same amino acid position, but resulting in a different missense (i.e. V394M) has been classified as Uncertain significance.

• Frequency: Genomes: not found (cov: 30)
• Consequence: DNAJC11 NM_018198.4 missense
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 4.53

Genes affected

DNAJC11 (HGNC:25570): (DnaJ heat shock protein family (Hsp40) member C11) Involved in cristae formation. Located in mitochondrial outer membrane and nuclear speck. Part of MIB complex. Colocalizes with MICOS complex and SAM complex. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.
