Genes affected
LAPTM4A (HGNC:6924): (lysosomal protein transmembrane 4 alpha) This gene encodes a protein that has four predicted transmembrane domains. The function of this gene has not yet been determined; however, studies in the mouse homolog suggest a role in the transport of small molecules across endosomal and lysosomal membranes.

not specified Uncertain:1
Uncertain significance, criteria provided, single submitterclinical testingAmbry GeneticsSep 01, 2021The c.587C>T (p.P196L) alteration is located in exon 6 (coding exon 6) of the LAPTM4A gene. This alteration results from a C to T substitution at nucleotide position 587, causing the proline (P) at amino acid position 196 to be replaced by a leucine (L). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
