The ENST00000849192.1(ENSG00000310339):n.232-16043T>C variant causes a intron change involving the alteration of a non-conserved nucleotide. Note: ENST00000849192.1 is not a MANE Select or MANE Plus Clinical transcript for ENSG00000310339; the reported annotation may differ from that of the MANE-designated reference transcript for this gene. The variant allele was found at a cumulative frequency of 0.754 (AC=114,675) in the gnomAD database across 152,102 control chromosomes, including 44,641 homozygotes. The grpmax filtering allele frequency (95% CI) is 0.841. In-silico predictor (BayesDel (noAF)) classifies this variant as likely benign. No clinical diagnostic laboratories have submitted clinical-significance assessments for this variant to ClinVar.
