Variant summary

Our verdict is Benign. The variant received -14 ACMG points: 2P and 16B. PM4BP6_Very_StrongBS1BS2

The NM_001034853.2(RPGR):c.2447_2461delGAGGGGAAGTAGAGG(p.Gly816_Glu820del) variant causes a disruptive inframe deletion change involving the alteration of a non-conserved nucleotide. The variant allele was found at a frequency of 0.00348 in 896,827 control chromosomes in the GnomAD database, including 7 homozygotes. There are 907 hemizygotes in GnomAD. It is difficult to determine the true allele frequency of this variant because it is of type DEL_BIG, and the frequency of such variant types in population databases may be underestimated and unreliable. Variant has been reported in ClinVar as Likely benign (★★).

Genes affected

RPGR (HGNC:10295): (retinitis pigmentosa GTPase regulator) This gene encodes a protein with a series of six RCC1-like domains (RLDs), characteristic of the highly conserved guanine nucleotide exchange factors. The encoded protein is found in the Golgi body and interacts with RPGRIP1. This protein localizes to the outer segment of rod photoreceptors and is essential for their viability. Mutations in this gene have been associated with X-linked retinitis pigmentosa (XLRP). Multiple alternatively spliced transcript variants that encode different isoforms of this gene have been reported, but the full-length natures of only some have been determined.
