Submissions by phenotype

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsDec 02, 2022The c.524A>G (p.N175S) alteration is located in exon 5 (coding exon 4) of the LDAH gene. This alteration results from a A to G substitution at nucleotide position 524, causing the asparagine (N) at amino acid position 175 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
