Genes affected

CLN3 (HGNC:2074): (CLN3 lysosomal/endosomal transmembrane protein, battenin) This gene encodes a protein that is involved in lysosomal function. Mutations in this, as well as other neuronal ceroid-lipofuscinosis (CLN) genes, cause neurodegenerative diseases commonly known as Batten disease or collectively known as neuronal ceroid lipofuscinoses (NCLs). Many alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Jul 2008]

ACMG classification

Verdict is Pathogenic. Variant got 14 ACMG points.

• PVS1: Splicing +-2 bp (donor or acceptor) variant, product NOT destroyed by NMD, known LOF gene, truncates exone, which is 0.108580105 fraction of the gene. No cryptic splice site detected. Exon removal is inframe change.
• PM2: Very rare variant in population databases, with high coverage
• PP5: Variant 16-28485962-AAGATTGCAATCATAATCAAGTTTTCTTTTCTTTCTTTTTTTTTTTTTCTTCCTGAGACAGAGTCTAACTCTGTCGCCCGGGCTGGAGTGCAATGGCACGATCTCGGCTCACTGCCACCACTGCCTCCGGGGTTCAAGCGATTCTCCTGCCTTAGCCTCCTGAGTAGTTGGGACTACAGGCACCCGCCACCACACCTGGCTAATTGTTGTATTTTTAGTAGAGACGGGGTTTCACCATGTTGGCCAGGCTGGTTTCCTGACCTTAGGCGATCTGCCCTCCTTGGCCTCCCAAAGTGCTGGGATTACAGGCGTGAGCCACCACACCCAGCCATGGCCAAGTTTTCTCTCCTTGGACCCCTCTCCCTCCCGGCTCAGGGCAGCTCACCTGGCCAGCAGCAGGGCAGGGATACCCAGCATGGACAGCAGGGTCTGCTGAGGGGAGAGGCCGGCCTGGGTGAGGCCCAGGTAGGACAGGGCCCCCAGCAGCCCAGCTCCCCCAGTCCCTGAGGACCACCAGGAGATCACGGCCCTGGGAAGGAGAACACAGGAACATTCAGGAGGACCTAGGCTGACCATGGGACAGCCTCTCCCCACACTCCCTGCTCCACCTGCTTACCTGGGGTAGAAGGCAGTGAGGGAGAGGAAGGTGACCTCCCCAAGGCCTGATGAGATGCTAGCGAAGACCACACCTGGGGGGAGGACAAGCACTGGGATGGTCACACCACACCTTGCCACACTGCCCAGGCCTCTAATGTGTCTGGCCATGGCCTCCTCAGTATCAGCTCATAGAGGCTCCAATAGATCCCATGCATAGGCCAGGTTCCAGGTCTGAAGCAGAGCCCCACTCCCCTGCGTGTCCCTTCATGGAGAGTGGCACCTCCATCCACCCAGTTATCAGACCAGGGGCAGACATGCACCCTTGATGTCTCTGCCCCTTCATCAGTCTTTTTCTTTTCTTTTCTTTTTGG-A is Pathogenic according to our data.
