Genes affected

POLR1H (HGNC:13182): (RNA polymerase I subunit H) This gene encodes a DNA-directed RNA polymerase I subunit. The encoded protein contains two potential zinc-binding motifs and may play a role in regulation of cell proliferation. The encoded protein may be involved in cancer and human immunodeficiency virus progression. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2013]

POLR1HASP (HGNC:13924): (POLR1H antisense, pseudogene)

PPP1R11 (HGNC:):

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=0.19484848).

The c.62C>T (p.S21L) alteration is located in exon 1 (coding exon 1) of the ZNRD1 gene. This alteration results from a C to T substitution at nucleotide position 62, causing the serine (S) at amino acid position 21 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
