Variant summary

Our verdict is Likely benign. The variant received -2 ACMG points: 2P and 4B. PM2 BP4_Strong

The ENST00000359906.8(SERHL):​n.947G>T variant causes a splice region, non coding transcript exon change involving the alteration of a non-conserved nucleotide. The variant was absent in control chromosomes in GnomAD project. In-silico tool predicts a benign outcome for this variant. 1/1 splice prediction tools predict no significant impact on normal splicing. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.

Genes affected

SERHL (HGNC:):

RRP7A (HGNC:24286): (ribosomal RNA processing 7 homolog A) Enables RNA binding activity. Predicted to be involved in rRNA processing and ribosomal small subunit assembly. Predicted to act upstream of or within blastocyst formation. Predicted to be located in nucleoplasm. Predicted to be part of CURI complex and UTP-C complex. Implicated in primary autosomal recessive microcephaly. [provided by Alliance of Genome Resources, Apr 2022]

SERHL (HGNC:14408): (serine hydrolase like (pseudogene)) Predicted to enable hydrolase activity. [provided by Alliance of Genome Resources, Apr 2022]

ACMG classification

Our verdict: Likely_benign. The variant received -2 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.76).
