Genes affected

PUDP (HGNC:16818): (pseudouridine 5'-phosphatase) This gene encodes a member of the haloacid dehalogenase-like (HAD) hydrolase superfamily. The encoded protein has no known biological function. This gene has a pseudogene on chromosome 1. Multiple alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2010]

PUDP (HGNC:):

ACMG classification

Verdict is Uncertain_significance. Variant got 3 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.827

The c.476A>G (p.H159R) alteration is located in exon 4 (coding exon 4) of the PUDP gene. This alteration results from a A to G substitution at nucleotide position 476, causing the histidine (H) at amino acid position 159 to be replaced by an arginine (R). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
