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]

ACMG classification

Verdict is Likely_pathogenic. Variant got 6 ACMG points.

• PM2: Very rare variant in population databases, with high coverage
• PP3: MetaRNN computational evidence supports a deleterious effect, 0.978

Collection Method: clinical testing

The c.271T>G (p.C91G) alteration is located in exon 2 (coding exon 2) of the KIAA1324 gene. This alteration results from a T to G substitution at nucleotide position 271, causing the cysteine (C) at amino acid position 91 to be replaced by a glycine (G). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
