Variant summary

Our verdict is Benign. The variant received -20 ACMG points: 0P and 20B. BP4_StrongBP6_Very_StrongBS1BS2

The NM_015909.4(NBAS):c.1093G>C(p.Asp365His) variant causes a missense change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0104 in 1,610,118 control chromosomes in the GnomAD database, including 101 homozygotes. In-silico tool predicts a benign outcome for this variant. Variant has been reported in ClinVar as Likely benign (★★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. D365E) has been classified as Uncertain significance.

Genes affected

NBAS (HGNC:15625): (NBAS subunit of NRZ tethering complex) This gene encodes a protein with two leucine zipper domains, a ribosomal protein S14 signature domain and a Sec39 like domain. The protein is thought to be involved in Golgi-to-ER transport. Mutations in this gene are associated with short stature, optic nerve atrophy, and Pelger-Huet anomaly. [provided by RefSeq, Oct 2012]

ACMG classification

Classification was made for transcript

Our verdict: Benign. The variant received -20 ACMG points.

BP4

Computational evidence support a benign effect (MetaRNN=0.008595169).

BP6

Variant 2-15478280-C-G is Benign according to our data. Variant chr2-15478280-C-G is described in ClinVar as Benign/Likely_benign. ClinVar VariationId is 446082.Status of the report is criteria_provided_multiple_submitters_no_conflicts, 2 stars.

BS1

Variant frequency is greater than expected in population nfe. GnomAd4 allele frequency = 0.00769 (1170/152238) while in subpopulation NFE AF = 0.0132 (900/68012). AF 95% confidence interval is 0.0125. There are 9 homozygotes in GnomAd4. There are 579 alleles in the male GnomAd4 subpopulation. Median coverage is 32. This position passed quality control check.

BS2

High Homozygotes in GnomAd4 at 9 AR gene
