Description

The c.175G>A (p.A59T) alteration is located in exon 4 (coding exon 3) of the CLN3 gene. This alteration results from a G to A substitution at nucleotide position 175, causing the alanine (A) at amino acid position 59 to be replaced by a threonine (T). Based on data from gnomAD, the A allele has an overall frequency of 0.002% (6/281296) total alleles studied. The highest observed frequency was 0.004% (1/24784) of African alleles. This alteration was detected in conjunction with another alteration in CLN3 in multiple individuals with CLN3- related disorders (Chen, 2019; external communication). This amino acid position is highly conserved in available vertebrate species. This alteration is predicted to be deleterious by in silico analysis. Based on the available evidence, this alteration is classified as pathogenic.
