Variant summary

Our verdict is Benign. Variant got -7 ACMG points: 2P and 9B. PM2BP4_StrongBP6BS1

The NM_000026.4(ADSL):ā€‹c.895A>Gā€‹(p.Met299Val) variant causes a missense change. The variant allele was found at a frequency of 0.000151 in 1,614,222 control chromosomes in the GnomAD database, with no homozygous occurrence. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Conflicting classifications of pathogenicity (no stars). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. M299T) has been classified as Uncertain significance.

Genes affected
ADSL (HGNC:291): (adenylosuccinate lyase) The protein encoded by this gene belongs to the lyase 1 family. It is an essential enzyme involved in purine metabolism, and catalyzes two non-sequential reactions in the de novo purine biosynthetic pathway: the conversion of succinylaminoimidazole carboxamide ribotide (SAICAR) to aminoimidazole carboxamide ribotide (AICAR) and the conversion of adenylosuccinate (S-AMP) to adenosine monophosphate (AMP). Mutations in this gene are associated with adenylosuccinase deficiency (ADSLD), a disorder marked with psychomotor retardation, epilepsy or autistic features. Alternatively spliced transcript variants have been found for this gene. [provided by RefSeq, Dec 2015]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -7 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
BP4
Computational evidence support a benign effect (MetaRNN=0.029456675).
BP6
Variant 22-40361520-A-G is Benign according to our data. Variant chr22-40361520-A-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 198981.We mark this variant Likely_benign, oryginal submissions are: {Uncertain_significance=4, Likely_benign=2}.
BS1
Variant frequency is greater than expected in population afr. gnomad4 allele frequency = 0.00084 (128/152336) while in subpopulation AFR AF= 0.00301 (125/41578). AF 95% confidence interval is 0.00258. There are 0 homozygotes in gnomad4. There are 66 alleles in male gnomad4 subpopulation. Median coverage is 32. This position pass quality control queck.
