Supplemental Figure 1. Sanger sequencing of SLC34A3 and rs28434439 alternative alleles.

Sanger sequencing of subcloned DNA fragments showing mutant (A) and wild type (B) alleles, demonstrating that the SLC34A3 mutant allele and the rs28434439 alternative allele are not linked together (Panels A through H). PCR sequences from subject III-6 shows heterozygosity (T/C) for rs28434439 (Panel I) indicating presence of paternal wild type allele (A), and by extension, confirming the maternal origin of mutant SLC34A3 allele. These observations confirm the imputation results that the shared haplotype between father and mother carries the SLC34A3 mutation.
