Integrated Genetics/Laboratory Corporation of America RCV000169590 SCV000696650 pathogenic Sjögren-Larsson syndrome 2016-07-08 criteria provided, single submitter clinical testing Variant summary: The ALDH3A2 c.471+1delG variant involves the alteration of a conserved intronic nucleotide located at the invariable GT site at the border of intron 3. One in silico tool predicts a damaging outcome for this variant along with 5/5 splice tools predicting the variant to result in the weakening/elimination of the splice donor site in intron 3. These predictions have been confirmed by studies investigating SLS patients who carried the variant and demonstrated that the variant results in altered mRNA and the absence of the full length protein product. This variant was absent in 121396 control chromosomes, but has been reported in multiple SLS patients in either homozygosity or compound heterozygosity with other splice site or frameshift variants, suggesting pathogenicity. In addition, a clinical diagnostic laboratory classified this variant as Likely Pathogenic via ClinVar (without evidence to independently evaluate). Taken together, this variant is classified as Pathogenic.
