Genes affected
CLN6 (HGNC:2077): (CLN6 transmembrane ER protein) This gene is one of eight which have been associated with neuronal ceroid lipofuscinoses (NCL). Also referred to as Batten disease, NCL comprises a class of autosomal recessive, neurodegenerative disorders affecting children. The genes responsible likely encode proteins involved in the degradation of post-translationally modified proteins in lysosomes. The primary defect in NCL disorders is thought to be associated with lysosomal storage function. [provided by RefSeq, Oct 2008]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -13 ACMG points.

BP4
Computational evidence support a benign effect (MetaRNN=0.014074415).
BP6
Variant 15-68229536-C-T is Benign according to our data. Variant chr15-68229536-C-T is described in ClinVar as Conflicting_classifications_of_pathogenicity. ClinVar VariationId is 205180.
BS1
Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.00023 (303/1315828) while in subpopulation SAS AF = 0.00362 (265/73256). AF 95% confidence interval is 0.00326. There are 9 homozygotes in GnomAdExome4. There are 224 alleles in the male GnomAdExome4 subpopulation. Median coverage is 31. This position passed quality control check.
BS2
High Homozygotes in GnomAdExome4 at 9 AR gene
