Genetic Variant ELAPOR1:p.Ser92Cys (chr1-109164499-C-G) – ACMG Classification: Uncertain_significance (2 pts)

Variant summary

Our verdict is Uncertain significance. Variant got 2 ACMG points: 2P and 0B. PM2

The NM_020775.5(ELAPOR1):c.275C>G(p.Ser92Cys) variant causes a missense, splice region change involving the alteration of a conserved nucleotide. The variant allele was found at a frequency of 0.0000243 in 1,606,612 control chromosomes in the GnomAD database, with no homozygous occurrence. 2/3 splice prediction tools predict no significant impact on normal splicing. Variant has been reported in ClinVar as Uncertain significance (★). Another variant affecting the same amino acid position, but resulting in a different missense (i.e. S92Y) has been classified as Uncertain significance.

Genes affected

ELAPOR1 (HGNC:29618): (endosome-lysosome associated apoptosis and autophagy regulator 1) Expression of this gene is induced by estrogen and the encoded protein has been characterized as a transmembrane protein. The encoded protein has been found in to correlate with survival in certain carcinomas (PMID: 21102415) and may be important for cellular response to stress (PMID: 21072319). Alternative splicing results in multiple transcript variants. [provided by RefSeq, May 2012]

The c.275C>G (p.S92C) alteration is located in exon 3 (coding exon 3) of the KIAA1324 gene. This alteration results from a C to G substitution at nucleotide position 275, causing the serine (S) at amino acid position 92 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
