Genes affected

SAP30L (HGNC:25663): (SAP30 like) Enables several functions, including non-sequence-specific DNA binding activity, bending; phosphatidylinositol phosphate binding activity; and zinc ion binding activity. Involved in negative regulation of transcription by RNA polymerase II. Located in fibrillar center and nucleoplasm. Part of histone deacetylase complex.

ACMG classification

Verdict is Benign. Variant got -12 ACMG points.

• BP4: Computational evidence support a benign effect (BayesDel_noAF=-0.87).
• BS1: Variant frequency is greater than expected in population sas. gnomad4 allele frequency = 0.0197 (2993/152244) while in subpopulation SAS AF= 0.0429 (207/4822). AF 95% confidence interval is 0.0381. There are 43 homozygotes in gnomad4. There are 1442 alleles in male gnomad4 subpopulation. Median coverage is 33. This position pass quality control queck.
• BS2: High Homozygotes in GnomAd4 at 43 gene
