The NM_003143.3(SSBP1):​c.404-1415T>C variant causes a intron change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.0358 in 152,340 control chromosomes in the GnomAD database, including 227 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 0.036 (227 hom., cov: 32)
• Consequence: SSBP1 NM_003143.3 intron
• Clinical Significance: Not reported in ClinVar
• Conservation: PhyloP100: -1.61

Genes affected

SSBP1 (HGNC:11317): (single stranded DNA binding protein 1) SSBP1 is a housekeeping gene involved in mitochondrial biogenesis (Tiranti et al., 1995 [PubMed 7789991]). It is also a subunit of a single-stranded DNA (ssDNA)-binding complex involved in the maintenance of genome stability (Huang et al., 2009) [PubMed 19683501].[supplied by OMIM, Feb 2010]

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.91).
• BA1: GnomAd4 highest subpopulation (SAS) allele frequency at 95% confidence interval = 0.144 is higher than 0.05.
