Comment on variant

Deletion of exon 8 from NG_007074.1 (ABCA12).

Until December, 2022, NCBI staff represented the HGVS for allelic variant 607800.0011 as the deletion of exon 9, not exon 8.

(2005) did not identify any mutations by sequencing of the ABCA12 gene, Thomas et al. (2006) used a combination of oligonucleotide arrays, multiplex PCR analysis, and SNP genotyping to identify a heterozygous deletion of exon 8. The exon 8 deletion was inherited from her unaffected mother. (less)
