Genes affected

SHPRH (HGNC:19336): (SNF2 histone linker PHD RING helicase) SHPRH is a ubiquitously expressed protein that contains motifs characteristics of several DNA repair proteins, transcription factors, and helicases. SHPRH is a functional homolog of S. cerevisiae RAD5 (Unk et al., 2006 [PubMed 17108083]).[supplied by OMIM, Mar 2008]

ACMG classification

Verdict is Uncertain_significance. Variant got 0 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• BP4: Computational evidence support a benign effect (MetaRNN=0.22095254).

Mar 19, 2024

The c.4442C>T (p.T1481I) alteration is located in exon 25 (coding exon 24) of the SHPRH gene. This alteration results from a C to T substitution at nucleotide position 4442, causing the threonine (T) at amino acid position 1481 to be replaced by an isoleucine (I). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
