Variant summary

Our verdict is Benign. Variant got -12 ACMG points: 0P and 12B. BP4_Strong BA1

The NM_139173.4(SLC9B1):​c.-1-3848T>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0903 in 152,214 control chromosomes in the GnomAD database, including 802 homozygotes. In-silico tool predicts a benign outcome for this variant. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

• Frequency: Genomes: 𝑓 0.090 (802 hom., cov: 32)
• Consequence: SLC9B1 NM_139173.4 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: 1.89

Genes affected

SLC9B1 (HGNC:24244): (solute carrier family 9 member B1) The protein encoded by this gene is a sodium/hydrogen exchanger and transmembrane protein. Highly conserved orthologs of this gene have been found in other mammalian species. The expression of this gene may be limited to testis. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Jul 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.88).
• BA1: GnomAd4 highest subpopulation (AMR) allele frequency at 95% confidence interval = 0.144 is higher than 0.05.
