The NM_001080517.3(SETD5):c.2347-7A>T variant causes a splice region, intron change involving the alteration of a non-conserved nucleotide. The gene SETD5 is a known oncogene (CancerMine: 2 oncogene, 2 driver citations). The gene SETD5 is a cancer driver gene (CancerMine: 2 oncogene, 2 driver citations). The variant has a gnomAD grpmax filtering allele frequency (95% CI) of 0.000000908, indicating it is observed in the general population. Note: a gnomAD entry for this variant shows a statistical allele-bias signature, consistent with mosaic/somatic contamination (e.g. age-related clonal hematopoiesis) rather than true inherited population frequency — this frequency should not be read as evidence of a common, benign germline variant. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

SETD5 (HGNC:25566): (SET domain containing 5) This function of this gene has yet to be determined but based on sequence similarity to other SET domain proteins it may function as a histone methyltransferase. Mutations in this gene have been associated with an autosomal dominant form of intellectual disability. Alternative splicing results in multiple transcript variants encoding different isoforms. [provided by RefSeq, Jul 2017]

SETD5 Gene-Disease associations (from GenCC):

• intellectual disability-facial dysmorphism syndrome due to SETD5 haploinsufficiency

Classification according to ACGS-UK Somatic Oncogenicity v2025

Classification was made for transcript:

Our verdict: Uncertain_significance. The variant received 1 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	O3Absent or very rare in population		Absent or extremely rare in gnomAD (AC ≤ 2) — O3 moderate; GnomAD: AF = 0.000001, AC = 0 — absent/extremely rare (O3 moderate [+2])
	B3Computational evidence does not support deleterious effect		Computational evidence does not support a deleterious effect; Splice-region variant — splicing algorithms predict no impact on splicing; supports B3
