Genes affected

TECPR1 (HGNC:22214): (tectonin beta-propeller repeat containing 1) This gene encodes a tethering factor involved in autophagy. The encoded protein is found at autolysosomes, and is involved in targeting protein aggregates, damaged mitochondria, and bacterial pathogens for autophagy [provided by RefSeq, Nov 2012]

The c.3310C>T (p.R1104W) alteration is located in exon 25 (coding exon 23) of the TECPR1 gene. This alteration results from a C to T substitution at nucleotide position 3310, causing the arginine (R) at amino acid position 1104 to be replaced by a tryptophan (W). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
