The NM_001080517.3(SETD5):c.3856delT (p.Ser1286LeufsTer84) variant causes a frameshift change. This is a loss-of-function variant that does not trigger NMD. The variant allele was found at a cumulative frequency of 0.00000205 (AC=3) in the gnomAD database across 1,461,712 control chromosomes (no homozygotes observed). The grpmax filtering allele frequency (95% CI) is 0.0000116. Splicing prediction tools (SpliceAI) predict no significant impact on normal splicing. Variant has been reported in ClinVar as Pathogenic/Likely Pathogenic (★★).

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 ACMG Germline Pathogenicity v2019

Classification was made for transcript:

Our verdict: Pathogenic. The variant received 13 points.

Apply	Criterion Code & Title / Strength	Strength	Rationale / Clinical Context
	PVS1Null variant in LOF gene		Non-NMD frameshift: ≥4 downstream pathogenic — very strong evidence preserved (PVS1); Frameshift (exon 23 of 23) at amino acid 1286 of 1442; NMD not predicted. 8 pathogenic variants downstream support preserved loss-of-function impact. A new stop codon is introduced in the shifted frame, truncating the protein to ~1368 amino acids (74 amino acids lost).
	PM2Absent/extremely low in population databases		Rare in gnomAD for AD/XL gene (popmax AF below threshold) — PM2 Supporting; GnomAD popmax AF = 0.0000116 — borderline rare for AD/XL gene (threshold 0.0001) — PM2 supporting.
	PP5Reputable source reports pathogenic		ClinVar 2-star pathogenic — strong (PP5); ClinVar germline classification: Pathogenic/Likely Pathogenic, 2 star(s).
