Genes affected

ARSA (HGNC:713): (arylsulfatase A) The protein encoded by this gene hydrolyzes cerebroside sulfate to cerebroside and sulfate. Defects in this gene lead to metachromatic leucodystrophy (MLD), a progressive demyelination disease which results in a variety of neurological symptoms and ultimately death. Alternatively spliced transcript variants have been described for this gene. [provided by RefSeq, Dec 2010]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -21 ACMG points.

BP4

Computational evidence support a benign effect (BayesDel_noAF=-0.82).

BP6

Variant 22-50626882-G-A is Benign according to our data. Variant chr22-50626882-G-A is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 93126.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BP7

Synonymous conserved (PhyloP=-2.29 with no splicing effect.

BS1

Variant frequency is greater than expected in population sas. GnomAdExome4 allele frequency = 0.000461 (674/1461142) while in subpopulation SAS AF = 0.00406 (350/86256). AF 95% confidence interval is 0.00371. There are 9 homozygotes in GnomAdExome4. There are 433 alleles in the male GnomAdExome4 subpopulation. Median coverage is 33. This position passed quality control check.

BS2

High Homozygotes in GnomAdExome4 at 9 AR gene
