Variant chr8-85465289-A-C details in Genebe, Genetics Data Aggregator

Variant summary

Our verdict is Benign. Variant got -10 ACMG points: 4P and 14B. PM1PM5BP4_StrongBP6_ModerateBS1BS2

The NM_000067.3(CA2):c.52A>C(p.Lys18Gln) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.000242 in 1,614,032 control chromosomes in the GnomAD database, including 7 homozygotes. In-silico tool predicts a benign outcome for this variant. 14/21 in silico tools predict a benign outcome for this variant. Variant has been reported in ClinVar as Benign (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. K18E) has been classified as Pathogenic.

Genes affected

CA2 (HGNC:1373): (carbonic anhydrase 2) The protein encoded by this gene is one of several isozymes of carbonic anhydrase, which catalyzes reversible hydration of carbon dioxide. Defects in this enzyme are associated with osteopetrosis and renal tubular acidosis. Two transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jun 2014]

ACMG classification

Classification made for transcript

Verdict is Benign. Variant got -10 ACMG points.

PM1

In a domain Alpha-carbonic anhydrase (size 256) in uniprot entity CAH2_HUMAN there are 8 pathogenic changes around while only 3 benign (73%) in NM_000067.3

PM5

Other missense variant is known to change same aminoacid residue: Variant chr8-85465289-A-G is described in ClinVar as [Pathogenic]. Clinvar id is 914.Status of the report is no_assertion_criteria_provided, 0 stars.

BP4

Computational evidence support a benign effect (MetaRNN=0.0049146116).

BP6

Variant 8-85465289-A-C is Benign according to our data. Variant chr8-85465289-A-C is described in ClinVar as [Benign]. Clinvar id is 2069442.Status of the report is criteria_provided_single_submitter, 1 stars.

BS1

Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.000131 (20/152298) while in subpopulation SAS AF= 0.00415 (20/4820). AF 95% confidence interval is 0.00275. There are 1 homozygotes in gnomad4. There are 14 alleles in male gnomad4 subpopulation. Median coverage is 31. This position pass quality control queck.

BS2

High Homozygotes in GnomAdExome4 at 6 AR gene
