Genes affected

PJA1 (HGNC:16648): (praja ring finger ubiquitin ligase 1) This gene encodes an enzyme that has E2-dependent E3 ubiquitin-protein ligase activity. This enzyme belongs to a class of ubiquitin ligases that include a RING finger motif, and it can interact with the E2 ubiquitin-conjugating enzyme UbcH5B. This gene is located in an area of chromosome X where several X-linked cognitive disability disorders have been associated, and it has also been found as part of a contiguous gene deletion associated with craniofrontonasal syndrome, though a direct link to any disorder has yet to be demonstrated. Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2010]

The c.1310G>C (p.G437A) alteration is located in exon 2 (coding exon 1) of the PJA1 gene. This alteration results from a G to C substitution at nucleotide position 1310, causing the glycine (G) at amino acid position 437 to be replaced by an alanine (A). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
