Genes affected
SRCAP (HGNC:16974): (Snf2 related CREBBP activator protein) This gene encodes the core catalytic component of the multiprotein chromatin-remodeling SRCAP complex. The encoded protein is an ATPase that is necessary for the incorporation of the histone variant H2A.Z into nucleosomes. It can function as a transcriptional activator in Notch-mediated, CREB-mediated and steroid receptor-mediated transcription. Mutations in this gene cause Floating-Harbor syndrome, a rare disorder characterized by short stature, language deficits and dysmorphic facial features. [provided by RefSeq, Feb 2012]

ACMG classification

Classification made for transcript

Verdict is Uncertain_significance. Variant got 0 ACMG points.

PM2
Very rare variant in population databases, with high coverage;
PP2
Missense variant in gene, where missense usually causes diseases (based on misZ statistic), SRCAP. . Gene score misZ 2.1272 (greater than the threshold 3.09). Trascript score misZ 3.6253 (greater than threshold 3.09). GenCC has associacion of gene with developmental delay, hypotonia, musculoskeletal defects, and behavioral abnormalities, Floating-Harbor syndrome.
BP4
Computational evidence support a benign effect (MetaRNN=0.076780885).
BP6
Variant 16-30738033-C-G is Benign according to our data. Variant chr16-30738033-C-G is described in ClinVar as [Conflicting_classifications_of_pathogenicity]. Clinvar id is 982905.We mark this variant Likely_benign, oryginal submissions are: {Likely_benign=1, Uncertain_significance=1}.

Submissions by phenotype

Inborn genetic diseases Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 27, 2023The c.7993C>G (p.Q2665E) alteration is located in exon 34 (coding exon 32) of the SRCAP gene. This alteration results from a C to G substitution at nucleotide position 7993, causing the glutamine (Q) at amino acid position 2665 to be replaced by a glutamic acid (E). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
