Genes affected
DNAJB6 (HGNC:14888): (DnaJ heat shock protein family (Hsp40) member B6) This gene encodes a member of the DNAJ protein family. DNAJ family members are characterized by a highly conserved amino acid stretch called the 'J-domain' and function as one of the two major classes of molecular chaperones involved in a wide range of cellular events, such as protein folding and oligomeric protein complex assembly. This family member may also play a role in polyglutamine aggregation in specific neurons. Alternative splicing of this gene results in multiple transcript variants; however, not all variants have been fully described. [provided by RefSeq, Jul 2008]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -14 ACMG points.

BP4
Computational evidence support a benign effect (BayesDel_noAF=-0.81).
BP6
Variant 7-157382328-G-A is Benign according to our data. Variant chr7-157382328-G-A is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 291131.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.
BP7
Synonymous conserved (PhyloP=-1.6 with no splicing effect.
BS1
Variant frequency is greater than expected in population sas. gnomad4_exome allele frequency = 0.0000254 (37/1459438) while in subpopulation SAS AF= 0.000256 (22/85956). AF 95% confidence interval is 0.000173. There are 0 homozygotes in gnomad4_exome. There are 25 alleles in male gnomad4_exome subpopulation. Median coverage is 32. This position pass quality control queck.
BS2
High AC in GnomAdExome4 at 37 AD gene.
